It was my first experience with airbnb and a very positive one. The room was as described, the adjacent bathroom might be too small for bigger persons, but I enjoyed it. Small fridge, tea/coffee and kettle available just outside the room.
Carol's brownstone is located in a nice neighborhood, close to the park. I felt safe walking alone in the evening. Grocery shops and restaurants in the close vicinity, one even across the street. The closest metro station about 12 minutes walk from the house and without a lift or elevator, the steep stairs somewhat inconvenient if you carry a suitcase. Local bus B54 will take you to Jay St.-MetroTech station (with lift) on the A line to JFK airport.
