The host was very helpful, kind and attentive, responding very quickly to any issues or needs we had during our stay! She gave us very clear instruction of how to get into the flat and left us many useful maps and guide books for the local area and NYC.
The flat itself was stylish, comfortable and generally tidy with a nice garden.
Morning coffee in the peaceful and private garden was a delight. We had a few cockroaches lurking in the fridge daily, but I think this was due to hot, humid weather and not the cleanliness of the fridge. No real issues with this.

I would recommend this flat on the basis of the host and the flat itself. Great hosts and a nice comfortable flat.
However, the area could be a little intimidating for first timers in NYC, for younger or for more vulnerable people. We met some of the nicest people in the Harlem area and also some of the weirdest and scariest. During the day the area has lovely, quaint little cafes nice restraints and a good supermarket nearby. However, the area can become quite intimidating from early evening onwards and so I would bare this in mind if you intend to stay in the Harlem area. You could potentially get into trouble if not careful and used to the city.
From our perspective, we were really glad to stay in the area as it was an opportunity to see an interesting community and a side to New York that is away from the usual tourist traps.
