Highly recommended. What's on offer is a separate, basement apartment with plenty of space, and good facilities. Deborah and Conrad are charming, civilised and helpful hosts. Park Slope is regarded as a fashionable and hip Brooklyn neighbourhood, and it certainly offers good restaurants and delis. Access to the subway system is good.
If you need to get to Manhattan regularly, for the theatre or whatever, then Brooklyn is a fair way out of the way, particularly at night. But the joys of nearby Prospect Park, and all the other delights of Brooklyn, make up for the longish midnight train journeys.
