Be's place was a great home base for our week in New York. We were there with our three kids (ages 1, 7, and 11) and the space was plenty big enough for the five of us. Be aware there is no TV but you'll likely be too busy enjoying the city to even notice. This apartment is super basic, little more than two beds, a (very comfortable) couch, small kitchen and even tinier bathroom. The kitchen is nice for preparing small meals or snacks but there is no dining table so you need to eat at the couch. The place was generally clean but could use a deep cleaning.
The main bedroom gets a lot of light from the street at night so that can make it hard to fall asleep.
During our stay, there was construction happening in the building but it didn't start early enough or go late enough to disturb us.
The location is great! Close to the subway and everything you need is right there- food, drugstore, market, etc. I'm a runner and it was nice being able to walk out the door and run along the waterfront or in Central Park.
I would definitely recommend Be's place. As long as you have the right expectations, you will be happy with your stay.
