Sergo is an excellent host he is ready to lend help when needed.
The apartment is on third floor(be ready for a small hike) with nice wooden floors on the stairs and the apartment, very clean and the picture of the living room does not give you the reality that you are on a lovely high view of Harlem streets, Saturday morning was real nice hearing the music coming from the church.
Location perfect 2 blocks away from lines 2 and 3(25 min to Times Square) on the 125 st station, you have a Whole Foods at 125 and another supermarket at 116 st with a nice seafood distributor infront(loved that they had fresh oysters and could steam the clams you buy). Good restaurants nearby in the middle of west Harlem ambiance.
Would definitely stay again
