Will and Rhians place is beautiful! It's very well decorated and kitted out. We found the bed extremely comfortable, and the whole place has a really cosy feel to it. It's in a brilliant location for exploring Bristol, and getting around town, and lots of great shops and restaurants are within a few minutes walk.
The only real negative we found, as mentioned below, was the noise from the family that live above. The earplugs kindly provided are great for night, but if you're planning to stay in during the day it's not so great. If you're visiting to spend the day out and about I would definitely recommend the place!
