Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenant reviews for Constantin Ilis's buildings reveal a mix of strong points and areas needing improvement. Residents consistently praise the friendly and helpful front desk and maintenance staff, responsive management, and well-maintained common areas like laundry facilities on every floor. The location and security with doormen are also well regarded. However, common concerns include aggressive rent increases, occasional unresponsiveness or slow communication from management, thin walls causing noise issues, some outdated amenities, and sporadic pest sightings. While many recommend living here due to staff and location benefits, a few highlight management's difficulty during lease renewals and a need for better tenant relations and building upgrades.

Reviews

Former tenant·4 hours ago

Was mostly happy with this building, lived here for 3 years across two apts

Pros

Building staff was excellent. Front desk was very friendly/helpful (never lost a single package here), and trash rooms were well maintained. Management was responsive and communicative. Laundry was on every floor, and I didn't have an issue with machine availability/upkeep (usually went late at night though) Elevators were reliable and relatively fast/modern I used Astound/RCN for Internet, and had no issues.

Cons

Aggressive renewal rates (always ~8%) Noise was an issue, especially after I moved from the 22nd floor to the 4th floor; the windows had poor sound insulation against highway traffic. The water pressure was a bit on the weaker side than I would have liked. Cooling was a mixed bag. No issues in my first apt in this building. My second apt here featured one wall unit that turned off every few minutes, and another wall unit that made popping sounds and ultimately ended up bursting into smoke + burning/chemical smells. Had 1 roach and 1 mouse over 3 years; not the worst but not zero either
