It's different, but certainly not a Tree House. It's an addition to the back of a large house with trees. Easy Uber ride to downtown. It's directly below the airport flight path, so if you like noisy airplanes you're in luck.
Kitchen is in main house where they also rent half a dozen other rooms. We enjoyed it, a little noisy with the planes, but it's cozy and different. Located just a 10 minute walk to Little Italy. We felt safe, very friendly staff, it's clean, easy parking on the street. Felt a little like a hostile with shared kitchen, rooms, open areas in the yard.
