Floods & Mold Nighmares

Pros

Fairly modern and generally quick to get to the city.

Cons

Our apartment on the ground floor was and continues to be listed as a 3 bedroom which is a blatant lie. This is a 2 bedroom at best with no living room or a 1 bedroom with a living room. The downstairs is an illegal “cellar”, not a basement, and CERTAINLY not a bedroom. My family and I lived in this apartment for just over 5 years and our bedroom which was in the cellar flooded 21 times during that period causing approximately $10,000.00 in personal property damage. We couldn’t just move upstairs because both of those rooms were rented out through Nooklyn. We tried to elevate all of our belongings 6 inches off of the ground using restaurant grade metal shelving and pallets, but, because we were under street level, when the sewers would back up in the winter, sewage water came down on TOP of us from the light fixtures in the ceiling. The landlord actually tried to hide the fact that we were living in the cellar when people from the bank came to do an inspection, and instead of removing the moldy dry wall and replacing it, only painted over it where the bank people wouldn’t be able to see it.

Advice to the owners

Be honest for a change.

Cute starter place to live.

Pros

It's fairly quiet inside. The people who live here keep to themselves and are generally friendly.

Cons

The water pressure is really bad and I'm the winter you're getting 10 minutes of mildly warm water TOPS. Also the windows here leak but you can control the heat level in your apartment so it evens out. The rent has gone up 200 dollars year after year after year.
