Extremely little to recommend. The oven wasn't working and the host had to cook part of our meal for us, including over hearing her friends mock us during the process. Kath showed worryingly little knowledge about how the annex worked. The microwave works until you put one of the plates in it, then it rattles constantly. The electric hob works but really smells.
This is not an "entire place", it's a private room and an extension of the house. Unlike other "entire place"'s which are clearly second homes, this feels very much like an annex no one has tried to live in for a long time.
The wifi doesn't work unless you are right by the entrance door and even then it's slow and spotty.
The box heaters make the room either a stuffy oven or ice box. The kitchenette is tiny, don't expect to be able to cook without washing up and vice versa.
The bedding and pillows are feather.
The location is at the top of a steep hill, even by Bristol's standards. Expect to be taking taxis back home if you have any kind of issues with inclines.
