This is a very large and pleasant owner-occupied duplex in Morningside Heights/West Harlem. The location was perfect for us because we were visiting family nearby. But it is really a great location for anyone because of the nearby subway station at 125th Street and St. Nicholas Avenue, which has express trains to midtown and lower Manhattan. The station at 125th and Broadway is about as close, but the 1 line is a local and offers no advantages for most visitors. There are many very good restaurants nearby, and food markets not too far away. The upper level has two skylights and is very bright and cheerful.
Owner occupied: drawers and closets will be full. This was not a problem for us, and we have faced this situation before. Just so you know.
Duplex. There are a few steps up from the street, then a full flight to the bedroom level, then another full flight to the dining room-kitchen-living room level. Definitely not handicapped accessible. If you are OK with stairs, the vast amount of space is well worth it.
We didn't meet the owners; they were traveling while we were there. But we had email correspondence with them before, during, and after our stay. They were very responsive to email, very helpful, and very friendly.
Bottom line: the next time we stay in that neighborhood, we will try to rent this apartment again.
