Location and value is prime. However, walls are super thin and noise levels can be high up to midnight. We heard tons of noises from neighbors from the bedroom and bathroom. The bathroom is private, but shares an unopenable/thin door with the neighbors (locked from our side, but we can hear everything they are saying - I’m assuming they can hear us too). Water pressure was dope. We had to check into the Airbnb through it’s sister hotel a block down across the street.
If you’re looking for just a place to sleep in union square this is the place for you. If you’re looking for more amenities like parking, a fridge, a microwave, and a view, etc.; this ain’t it. Nevertheless, for us, it was great experience, value, and stay.
