Reviews

Former tenant·10 months ago

Landlord is a money hungry bully

Pros

There are cameras in the building. Not that they get checked.

Cons

The landlord is horrible. He harasses and bullies his tenants to get extra payments not just from the city but the tenant as well. The windows are not sealed properly so whatever the temperature is outside it’s worse inside. When it rains it leaks throughout the apartment. The landlord does not handle those issues he sends you to what should be the super who also does not help.

Easy and Comfortable

Pros

Small building, regularly cleaned, responsive and responsible management.

Cons

No space for bikes and can’t lock up our front. No master locks allowed in case of emergency either.
