This is the third time I have stayed at Interfaith Retreat Rooms, I adore this place, its got good energy, sweet hosts and really quiet compared to all the NYC noise outside.
Location is great, the price is great and the place is super clean and well taken care of. The small rooms can fit your suitcase under the bed, there is space overhead for clothing, etc. The bed is a XL twin, I am 5'11 and 200 lbs and I fit comfortably. Wear earplugs if you want it super quiet, but after hours the place is so quiet you will wonder if you are the only one there. My last stay i think the room I was in was under the heater, so it was a bit warm, I run warm so I may ask for a room towards the back. I recommend this place to anyone that wants to be really close to penn station, times square and right in the middle of Chelsea. Two thumbs up!
