Nia's place is exactly what it promises. In a safe neighborhood, in an old townhouse with interesting wooden touches and plenty of noise from the train. I personally didn't have trouble as I adapted quickly and enjoyed my stay. The spot is really close to Manhattan, only 7-10 minutes away from Lexington avenue by train.
Staying at Nia's place means you practically have the place to yourself and the other guests.
It pays to wake up earlier than the rest to use the bathroom as too many guests means some waiting time is involved. I will surely stay again!
