The best thing about staying at Martin's is that you are very well connected to the city. Most places in Manhattan are about 30 minutes away by subway.
The apartment is nicely decorated and clean, but a little run down. Some might appreciate the rustic feel though. The room I stayed in was a central room (with no external windows). The air conditioning unit for this room is actually in the living room and cools through high windows... So it got a little bit warm being summer. A table fan in the room helped fixed that though.
Martin himself is friendly, easy going and easy to communicate with. He was very sweet to carry my luggage up to the penthouse. Really appreciate that.
All in all, I had a comfortable stay!
