Niko's apartment is close to nearly everything in Manhattan. If you're happy to walk, you can walk pretty much everywhere, otherwise there are plenty of subway stations nearby. There are tonnes of food options around, and plenty to do.
The room itself is a good size, the bed is comfy and everything was clean. The wifi was very quick! Niko is so friendly, he gave us ideas on what to do and was just great to chat to.
We would happily stay here again next time we're in New York.
