I stayed at Joe's place for a couple of nights. Since I just needed a place to sleep, I booked it mainly because of the very high rating and the presence of private off-street parking.
The room was clean, the bathroom was equipped with toiletries and my stay was overall okay, but I think that a rating of 4.8 is way too much and may be misleading.
Just a couple of things to be aware of:
1) The description is accurate, but the space is even smaller than how it looks in the pictures. It is okay for one person but may feel very tight for 2 people.
2) With 2 guests, the bathroom "door" doesn't really give much privacy.
3) Insulation should be improved. The windows are old, single-glazed and the one in the bathroom wouldn't close properly. As a result, I could hear dogs barking overnight and early in the morning. I recommend bringing earplugs.
Other than that, no big issues: Joe is very responsive, the neighbourhood is okay and the room is quite good value for money.
