Had a brilliant 7 night stay here. The rooms are very small but functional, and having your own (locking) room in a hostel is pretty fantastic. Toilets were kept very clean throughout my stay, and were well stocked (2 showers/2 sinks/3 cubicles). The Breakfast area is an amazing touch, and having a space to relax in/sit in was lovely. Also the provided breakfast food options were great!
Alex is fantastic, he was incredibly warm and helpful. I never had any worries while there. There is always someone at the office, and 24 hour access was very welcome.
Location is absolutely perfect. Easy to find and incredibly central, but also not too noisy. Penn Station is a few minutes walk uptown, then the 28th street 1 Subway station is very close. Great food options nearby (Pizza Suprema is fantastic if you want a slice, and only a block away).
I do advise using earplugs, unless you are a very heavy sleeper. Doors closing can be surprisingly loud, as the room is actually very quiet. Was kept nicely cool (air con) and the wifi (and wifi coverage) was good.
All in all, I would heartily recommend it for anyone visiting the city, especially for short trips. Incredible value, a calm atmosphere to escape the chaos of the city and lovely warm and friendly people running it. May well return in the future!
