Karen's place is a fairly large brownstone located a block from the Manhattan bound R train in Brooklyn, making it easy to get into Manhattan but difficult to get to other parts of Brooklyn (like Williamsburg). The house has a nice garden, and spans three (?) floors, but most of the doors were locked - including to the basement.
I stayed here on short notice - we booked a day before arrival - so it should definitely be noted that Karen was accommodating. She left a nice welcome basket with informative instructions and was quick in all her responses.
But, I found the overall experience to be uncomfortable - we didn't have access to a proper bedroom; instead there were two twin beds placed in a small and very hot space above a long flight of stairs. All of the locked rooms were also unsettling - not to mention the lights flickered on and off a few times, which made for an uneasy sleep. We ended up taking sheets down from the bedroom and sleeping on the couch.
