I was there visiting a friend for a few days and I had a good time. Didn't see that much of David due to his work schedule, but he was very friendly and accommodating. My late arrival (around midnight) wasn't a problem at all.
The room was just like in the pictures: not very big, but great if you just need somewhere to sleep and are out a lot. The house is clean and the shower works perfectly (which is worth A LOT).
There is a dog in the house (he's pretty big, but a real sweetheart), but David usually keeps him shut in his room when he is out, so no worries there.
The bus station Morris Road of the line 24 is literally two minutes from the front door. The bus will take you right into the city, which is great if you don't have a car. (Take care when getting there by bus though, the station is easily missed because the bus will not stop automatically and the stops are usually not announced. I used google maps to check my location and press the stop button at the right time. You could also ask the bus driver beforehand.)
All in all: This room is for you if you just need somewhere to sleep and your trip is not all that long. You should also be ok with a dog.
I would definitely return.
