Conrad is a lovely host. He's easy to contact, and is incredibly gracious, and helpful.
The place is clean, comfortable and quiet. It is a nice brownstone on a fairly quiet street.
It is close to some historic places in Harlem, such as the Apollo theatre, Sylvia's restaurant and some amazing murals.
Nice coffee shops are "I like it Black" and "9 Tails" which is also a plant shop and hardware store.
The subway is fairly close to get everywhere you need to in NYC.
