Me and my friend had separate reservations, but the awesome crew helped us end up in the same dorm.
We had a 4-bed dorm ensuite which we stayed 9 nights in and was very pleased with the quality ocg basically everything. The room was cleaned every day and the beds were made. Towels could be exchanged as much as we wanted to. Slippers and soap included in the deposit for the towel.
The only thing we missed was some kind of scale to weigh our luggage. The one they had was apparently broken. Some kind of scale would be nice.
The overall cleanliness of the shared bathroom was very good. They were cleaned at least twice a day, which felt nice.
The AC was working hard during our stay due to the warm temperatures outside. I had the bed closest to the AC, and my sleep was mildly disturbed by the sound and the blasting air. But not much.
The location at 200E 34th street is 15 minutes walk from Penn Station, so it's a great place to stay for a great access to New York City. With a subway stop just two avenues away we could travel like the wind below the streets.
One thing to mention is the showers inability to produce my liking of shower temperature, even if the handle var stationary the temperature went up to scolding temperatures. Though this is a thing for all the American showers I've tried. Not singular to NYBI.
Thank you for a very nice stay!
