don’t be fooled by the outside

Pros

It’s not the worst building in the area

Cons

This building still sucks - laundry room hasn’t been open in almost two years because of bed bugs. hallways are never clean and littered with trash. packages are stolen in the lobby. There is one elevator in a building that clearly needs two plus the stairs are not sturdy so you always feel like you will trip. constant infestation of bugs and rodents. Baby mice run around in the hallways. I’ve had to buy special treatment for roaches because it used to get so out of hand.
