i stayed at Pod Hotel (2 Ave & 51st) it was cheaper than most of hotels in manhattan - around $120ish? i forgot the exact price.
the hotel is clean, and modern looking, but you have to share a bathroom with three other rooms. i was worried about that, but it worked out fine. there are 3 other bathroom on the floor and you can check which one is available (there is this blinking light thingy in the room and numbered accordingly), but i ended up using one bathroom right next to my room all the time...it was available whenever i wanted to use. Bathroom is very very clean too! it's NOT like a community bathroom in dormitory.
if you wanna call them and make a reservation, that would work. that's what i did. While you are on the phone, they'll send you a confirmation email, so i believe it is pretty safe.
sorry...my post got a bit long...😀
good luck!!! the interview was very laid-back, and the school was AMAZING🙂
