Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews for buildings managed by John Koors indicate a mixed bag regarding tenant experiences. Many residents appreciate the cleanliness and welcoming staff, along with decent amenities such as responsive maintenance and solid garbage management. However, recurring issues with heating inconsistency, elevator reliability, and management responsiveness have been frequently noted as key drawbacks. Some tenants feel that the value offered may diminish as rent stabilization ends, leading to higher living costs. Overall, while the properties boast attractive locations and features, the management could significantly improve communication and maintenance efforts to enhance tenant satisfaction.

Reviews

Former tenant·just now

decent high rise apartment, somewhat poor management

Pros

- decent location with lots of trains - generally clean - great staff - “acceptable” prices for nyc standard

Cons

- heating availability very inconsistent during the winter - water shuts off with very little notice sometimes - elevators broken more than they should - my friend who referred me to the building never got his referral bonus (which isn’t much to begin with)

Advice to the owners

make the necessities like heat/water supply better

Former tenant·1 month ago

Quiet, Spacious, Great AC - but had trouble with heat in winter

Pros

- The most spacious place we've ever lived, huge kitchen and storage, spacious bathroom, comfortably fit a large media console and keyboard and 2 WFH desk set-ups (one in living room and one in kitchen) - Online portal and lease management very easy to access - Great value for the price and located near many grocery stores, target, fast casual food options - Easy access to waterfront in brooklyn heights and farmer's market - Easy access to Cobble Hill and atlantic ave - Pretty large gym that was almost always empty - Yoga studio - Laundry was easy to manage via mobile app

Cons

- The immediate surrounding neighborhood has some sketchy folks sometimes. I never felt in danger or unsafe but it is something that sometimes dissuades me from spending too much time outside in immediate vicinity. - Heat seems to be only available at a certain time, which caused neighbors to be upset. I never personally had any issues
