We stayed for 3 nights at Birgitta's apartment. We have 2 young children and this was one of the best vacation experiences we've ever had. Because the apartment is a duplex, we were able to entertain a couple of friends while the kids slept upstairs. Besides being spacious, the apartment is clean and conveniently located. Birgitta was an extremely helpful and accommodating host. I'd highly recommend this apartment to anyone wishing to explore the Park Slope area.
