Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenant reviews for buildings managed by Grzegorz Wiszniewski reveal a mixed management reputation. Some tenants appreciate his responsiveness and good garbage management, valuing spacious units and convenient locations. However, others report serious issues with neglect, poor maintenance, unaddressed pest control, and problematic heating. Several tenants faced challenges with disruptive neighbors and noise, and some criticized the landlord's attitude and handling of disputes, including rent hikes and eviction attempts. Cleanliness and upkeep vary widely across buildings, with some units arriving dirty and others well-maintained. Prospective renters should expect inconsistent management, with occasional promptness overshadowed by reports of neglect and contentious landlord-tenant relations.

Great value, nice place

Pros

Owner is very responsive and fixes things right away. Good trash management. Overall everything usually works well, few issues. Pretty good deal.

Cons

Walls within the apartment are thin, but I don't hear other units. Can't control the heat in my unit. Pretty normal things, nothing bad to say overall about the place
