We stayed here a week in August, family of three. The place is great, you have your own floor (two rooms and bathroom) plus you can use Christines kitchen and garden as you please.
Park Slope is a great area, and great restaurants, shops, the park etc. is just around the corner. Great local feel. Manhattan just 15 minutes away by subway.
Christine is a great host, really enjoyed our conversations over morning coffee and her suggestions as a NYC native were very good and useful.
Highly recommended.
