Paper thin walls

Pros

Apartment looked nice, super was responsive on his working days (not really over the weekend), great central location. Had an ant problem for a bit as others mentioned but exterminator was quick to fix. Never saw any pests other than ants

Cons

Walls and floors are paper thin. I could hear every single conversation my neighbors had if we were in the same room at the same time, including upstairs and downstairs. Apartments used to get really hot with no way to fix it
