Advice to the owners

get it together

Former tenant·6 months ago

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.
