While the room is small, as other reviews have noted, my wife and I found it to be perfect for our one-night stay. We were in town for an event and basically needed a clean and convenient room to sleep in, and that's exactly what we got. The house is less than a block from the Journal Square PATH station, and Freddie, the caretaker, is as nice and helpful person as you could ask for.
One thing: parking on the street was virtually impossible on a Saturday afternoon, but there is a 24-hour pay lot on the nearby cross-street that we thought had very reasonable rates so we went with that. Worth mentioning because you may need to walk a block or so.
