We felt quite comfortable in the falt. The flat is equipped in everything one may need. Our teenagers did not complain either, althoug they slept in bunk bed that was really comfy.
The only thing is that subway takes about 45 to 1h 15 mins to get to Manhatan, but this we knew in advance. The souranding is safe we did not face any problems nor any blusters. Our host was prepared for our arrival and there was always someone on standby that we could text or call in any need.
