We stayed 4 weeks at this place and were happy with it. The neighborhood is very pleasant, the next subway station is near, and many nice places and shops in Park Slope are in walking distance.
We found the apartment as described with a large living room and a good bedroom, all very clean. As it is a basement apartment there is not much daylight though. Internet access worked promptly, but there was a problem with the tv cable setup which should be fixed by now. Helen was a very friendly host, always reacting promptly to our text messages and striving to make our stay really satisfying. She even brought additional kitchen implements and made it possible for us to have friends over for dinner. We therefore felt very much at home.
