Fabulous location and great host--she was very flexible with check-in and check-out times, which helped our trip so much. The apartment is in an old brownstone, and has lots of character and lovely decor. This is Karen's home which she makes available to guests, and she stays elsewhere during the time you are there. I had only one problem which had to do with summer heat--the living room area can get very hot on hot days, and is difficult to cool. Sleeping is fine, as there are window units in each bedroom.
