| Project | Overall | Structure & systems | Management & living |
|---|---|---|---|
| SUMMIT One VanderbiltEast Midtown, New York | 8.7/ 10 | —/ 10 | 8.7/ 10 |
Google’s 4.6/5 aggregate from 15,557 guest reviews sets the level and converts to 8.8/10 under the requested curve. Tripadvisor’s 4.5/5 from 4,445 reviews is directionally consistent, while recurring praise and recurring queue/disorganization complaints produce a modest net downward adjustment to 8.7/10. This is a guest-experience score for an observation deck, not evidence of residential living or building systems. | |||
no notes returned no links returned | Guest reviews consistently praise the views and the immersive installations: one called the skyline “magnificent,” while another said the interactive elements set SUMMIT apart. Operational feedback is mixed: reviewers report “6 different rooms of lines,” a one-hour delay for a timed entry, and one January 2025 reviewer described staff as “completely unprepared,” although other reviews call the guides “wonderful,” “personable & knowledgeable.” | ||
| One Vanderbilt AvenueEast Midtown, New York | 8.3/ 10 | 8.5/ 10 | 4.9/ 10 AppRecs (One Vanderbilt tenant/visitor app) 2.6/5 · 9 reviews · apprecs.com AppRecs (One Vanderbilt tenant/visitor app) publishes 2.6/5 from 9 reviews. Adjusted for where resident ratings usually fall, and weighted toward the 6.5 midpoint (more strongly the fewer the reviews), that gives 4.9. |
The largest review base is the guest Google aggregate for SUMMIT One Vanderbilt, published as 4.6/5 from 15,557 reviews, converting to an 8.8 anchor under the requested curve. The building-specific Tripadvisor entry is only one review, while the AppRecs score covers an access app and has nine ratings; the documented elevator malfunction warrants a modest downward adjustment, leaving 8.3 overall. | |||
Published technical and facilities coverage describes LEED v4 Gold, WELL Core Platinum, MERV 16 filtration, bipolar ionization, HEPA filtration and ongoing water/HVAC testing transparency. The main serious failure reported was the March 2023 external-elevator incident: coverage says the car fell three stories onto a catching spring, producing a tremor that occupants described as “very scary”; no injuries to building occupants were reported, although three mechanics had minor injuries. | Published descriptions praise the Vandy Club as a “beautiful” and “well serviced” tenant space, while the observation-deck operation is described as “very high touch” and “very friendly and user-friendly.” Counterevidence is limited but concrete: one tenant said the access app was “Completely unreliable,” and guest summaries mention long lines/crowding and that the experience can be expensive. | ||
| 410 Tenth AvenueMidtown West / Hudson Yards, New York | 8.2/ 10 | —/ 10 | 8.2/ 10 |
The largest published review base located is the building-specific 4.4/5 from 19 reviews, which sets the anchor at 8.2/10 under the stated conversion curve. No recurring complaint or praise theme met the reporting threshold, and the 4.1/5 source has fewer than 10 reviews and therefore does not qualify as a scoring anchor. | |||
Published project material describes a full façade restoration, new high-performance insulated windows, efficient HVAC systems and conversion of freight elevators to destination-dispatch passenger cabs. A review nevertheless said, “Ventilation / HVAC seems on economy mode as the air can be stuffy at times”; this is a single operational report, not evidence of a recurring structural failure. | The readable feedback is generally favorable: one reviewer called it an “Awesome office space,” and another described it as a “Nice venue for the AWS community.” Negative operational comments included “Shame the downstairs coffee and sandwich place closed,” stuffy air, and a “Strange policy for entry into the building”; these are workplace/visitor observations rather than resident reviews. | ||
| 7 Dey StreetFinancial District, Lower Manhattan, New York209 units | 7.6/ 10 | —/ 10 | 7.4/ 10 |
Openigloo’s 4.7/5 building rating is the only published resident aggregate located and therefore sets the anchor; its direct conversion is approximately 9.1/10. Because it rests on only three reviews, the result is pulled toward the required 6.5 small-sample level, producing 7.4/10; no structural score is assigned because the material found is compliance information rather than a scored systems assessment. | |||
Openigloo reports “No open violations” and lists zero Class A, B and C violations for the building, including no reported rodents, mold, inadequate heat or hot water, or defective building parts. This is a compliance snapshot rather than an engineering assessment, and no resident review supplied a specific structural, plumbing, HVAC or waterproofing observation. | The visible renter feedback is favorable: residents describe “wonderful staff, clean building, not overcrowded” and say “amenities are amazing”; the page’s review summary also characterizes management as responsive and the gym as rarely overcrowded. The same source records practical complaints that “elevators take awhile,” packages can make the lobby look overcrowded, and security concerns were raised because of doorman limitations; the latter summary is older/aggregated evidence rather than a dated current-status finding. | ||
| 15 BeekmanFinancial District, Lower Manhattan, New York | 4.0/ 10 | 3.5/ 10 | 4.0/ 10 |
No applicable platform published a rating for 15 Beekman: DormScouter and OpenIgloo both showed no reviews or ratings. The score therefore follows the four resident/workplace accounts actually read, which were negative or mixed rather than positive, with additional serious historical reports about the dryer fire and emergency preparedness; confidence is limited because the strongest evidence is from 2023–2024 and does not establish that every issue remained current on 2026-10-15. | |||
Published resident reporting describes “extremely faulty” residential elevators and a January 2024 laundry-room dryer fire that damaged nearby machines and injured three students. One student reported that the stairwell was blocked by smoke and that no fire extinguisher was found, while the laundry room was expected to remain unavailable for three weeks to a month; these are historical reports, not confirmation of conditions on 2026-10-15. | Residents praised the social atmosphere—“it makes it easier to build a community”—and the amenities, especially the 25th-floor kitchen. However, published accounts describe crowded suites, delayed responses to unsafe door problems and security that was “sometimes very rude and not very responsive”; a 2024 campus report also recorded complaints about wrong orders, long waits and food quality in the building’s cafeteria. |
