We spent in John's house 11 days in August 2015.
The apartment is located on 5th floor (it's acutally 4 floors to climb since floor one is almost at ground level).
The apartment is pretty small, but I guess in NYC it's pretty standard with two windows next to the bed.
We didn't use the kitchen at all since we had all our meals out, but if you plant to have at least breakfast at home it's a nice feature.
The room has air conditioner (it's not very strong, maybe it needs to be fixed just to give it some extra strenght for hotter summer days of NYC) and a fan.
The apartment is furbished with bed linen, towels, plates, glasses etc...
We had very nice stay and John was really kind to us, since he waited for us in a 2 hours delay and left us the fridge full of breakfast food he just bought for us (orange juice, bagels, butter, milkshakes and some pastries).... it was really a great welcoming !!
We haven't seen him during our stay since he was away for his job but we kept in contact with emails if needes.
He gave us infos about the places to visit, how to get around and so on: it was my first experience on airbnb and I couldn't find a better host !

The neighbour is quiet an peaceful, expecially on sunday mornings.
People are friendly and the street (fredrick douglass blvd) is full of shops.
Nothern Central Park is 7 blocks away and just a 10 minutes walk.

There's a Starbucks one block away or a nice patisserie (Patisserie Des Ambassades) for guys who want to enjoy a breakfast with cappuccino and a croissant.
The Harlem Tavern (located one block away) is a gret place to go, lots of young guys, great food and good vibes: go for a Sunday Brunch and you'll have a gret time.
There's a huge supermarket (Best Market) one block away that makes the best brisket i've had in NYC; seriously, it was better then the one I had in Dinosaur BBQ, so juicy and flavorful.
One more thing: DO NOT MISS the cookies from Levain Bakery, just on the other side of street, they are absolutely fabulous but a bit pricey (4 dollars each)

The subway is one block away (116th street) with local lines B and C that take you downtown manhattan in 10 minutes: we just bought a 7 days ticked and enjoyed unlimited trips.

Overall it was a very nice stay for a good price (considering overall prices for NYC accomodations).
I would recommend !
