This is a quaint and cute space for young travelers. If you are traveling alone, this is great. With more than one person though, I’d say the futon is not super comfortable to fit two people and that the bunk bed can be squeaky and a bit painful to climb up to (the ladder had skinny steps that would hurt your foot a bit when you put your full weight on it - for reference, I am 125 pounds). The rest of the private space is excellent and totally functional!
Please be aware of the shared toilet. You are 1/6 tenants on the floor and the building is old so the bathroom and shower are not super ideal but they work totally fine.
The area of this place is not the best, to be honest. The listing says Chelsea, but it is much closer to Hudson Yards and Penn Station. Although you can easily walk to nicer parts, the place itself is on a street with some homeless people and sketchy people at night. You may get asked for change or see some people who do not look well (passed out on the street in half their clothing). The 7/11 nearby (I’d go to get water) also has a lot of lurkers waiting by the door to ask you for something. You will certainly need to use your street smarts!
