| Project | Overall | Structure & systems | Management & living |
|---|---|---|---|
| Kasaba Evleri — 1. Etap (16 villas)Ömerli-Çekmeköy, İstanbul16 units | 8.7/ 10 | —/ 10 | 8.7/ 10 |
The 4.67/5 aggregate from 12 reviews sets the level; on the requested market-style 1–10 conversion it is approximately 9.0 before commentary. The evidence is strongly positive on setting and lifestyle, but the single serious management allegation lowers the resident-experience score; no structural score is assigned because no building-fabric or systems review evidence was published. | Not found in sources: Limited review detail | ||
no notes returned no links returned | Reviews repeatedly describe the setting as peaceful and nature-integrated, including “Doğayla iç içe mimarisi” and “Tam doğanın içinde”; another reviewer praises the “kaliteli bir Site.” The operational record is limited, but one reviewer alleged that site management was silent over a disputed employment exit, and another described the location as “biraz uzak”; the listing also records extensive social facilities including indoor/outdoor pools, spa and sports courts. | ||
| Litus İstanbulAltunizade-Üsküdar, İstanbul115 units | 7.3/ 10 | —/ 10 | 7.3/ 10 |
Google Reviews/Maps has the largest published review base at 13 and sets the level: its 4.1/5 converts to approximately 7.5/10 under the stated curve. Yandex provides a lower, smaller-base signal, while repeated praise modestly offsets the adjustment; no independent structural rating was published, so structure remains unevidenced rather than marked down. | Not found in sources: No resident structural feedback · No published maintenance reports · No published plumbing feedback · No published HVAC feedback · No published leak/waterproofing feedback | Not found in sources: Limited resident-review evidence · No published management/cleanliness sub-scores | |
The published project material states that Litus İstanbul was built to the latest earthquake regulation on “Sert Zemin (ZEMİN B)” with a raft foundation, C35-C40 reinforced-concrete columns and B420C ribbed steel. A July 2024 report says the project was completed and occupied, but the sources opened contain no resident-written reports or platform sub-scores about leaks, lifts, plumbing, HVAC or other in-use defects; the structural claims therefore remain developer/project-report statements rather than independently reviewed performance. | The accessible reviews praise the staff—“Çok ilgili, bilgili ve kibar”—and describe the location as “Altunizade nin yeni yüzü,” while several reviewers object to prices around one million US dollars for smaller units. One March 2026 review reports asking twice for a written offer and being unable to obtain one, so the positive service picture is not uniform; the project material advertises a pool, fitness, basketball area and security, but these are amenities/claims rather than resident ratings. | ||
| Ege Perla Alışveriş MerkeziKonak, İzmir | 6.2/ 10 | 6.0/ 10 | 6.2/ 10 |
Yandex Maps provides the largest published review base at 3.8/5 from 108 ratings, converting to approximately 6.4/10 under the supplied curve; Haritane's 3.9/5 from 22 ratings is directionally consistent. The reported operational complaints justify a modest downward adjustment, while praise themes prevent a harsher result; the structure score is limited to the published lift, escalator and cooling evidence. | |||
Published visitor feedback identifies operational building-system problems rather than structural damage. Haritane reviews say the lifts and escalators did not work properly, one later update says the lifts were working again in April while some escalators remained out, and another visitor reported that “%90 ı çalışmıyor”; Şikayetvar separately records a December 2024 complaint that one lift was stuck on the third floor. A 2023 complaint also says store air-conditioning was not working in hot weather; no published evidence located here establishes framework, plumbing, waterproofing or electrical-infrastructure failure. | Daily-life feedback is mixed but leans negative: visitors describe “çoğu işletme kapalı,” repeated parking or charging difficulties, and customer-service problems, while one review calls the security staff “çok saygılı” and another praises the clean toilets. Yandex records both “Boş bi awm ... bi çok dükkan boş” and “Cok guzel bir yer. Tavsiye ederim,” showing that the current published experience is not uniform. | ||
| Manzara AdalarKartal, Istanbul975 units | 5.9/ 10 | 5.8/ 10 | 5.4/ 10 |
Placera’s building-specific aggregate of 3.67/5 from 100 reviews is the anchor, converting to 6.0/10 on the requested market curve. The reported commentary is mixed: amenities, views, quietness and location are repeatedly praised, but recurring management, elevator, security/staff, pet-control and upkeep complaints lower the resident-experience estimate to 5.6 overall. | |||
Yapı ve sistemler hakkında olumlu yorumlar, “evlerin içi çok sessiz”, “bina içi koridor ve asansörleri geniş ve ferah” ve “yapı kalitesi ... muhteşem” ifadeleriyle geliyor. Buna karşılık birden fazla yorum asansörlerin sürekli bozulduğunu, 40 kata iki asansörün yetmediğini veya asansörlerin arızalı hissettirdiğini söylüyor; ayrıca tekil yorumlarda elektronik/dijital güvenliğin beklentinin gerisinde kaldığı ve bazı kapıların söküldüğü belirtiliyor. | Günlük yaşam deneyimi güçlü sosyal olanaklar ve manzara ile olumlu anlatılıyor: bir sakin “açık kapalı havuz, spor salonu, sauna bilardo kütüphane herşey var” derken başka biri güvenliği “üst düzey” buluyor. Ancak yönetim ve hizmet tarafında tekrar eden şikâyetler var; yorumlarda “Yönetim ... hiç bir şekilde ilgilenilmiyor”, “güvenlikler ... saygısız ve kaba” ve girişlerde köpeklerin sakinleri korkuttuğu belirtiliyor. |
