Prue is a nice and knowledgeable host. She recommended several great restaurants and were very detailed in telling us how to spend our time in Bristol.
Her place is quite accessible to the centre (around 15 mins by bus) and is right on the Gloucester Road.
As the room is right next to the road, there might be some noise from late night passerby, but nothing too serious. The room is roomy, clean, and has everything you need. You can even help yourself to some cereal downstairs. There are supermarkets nearby.
I highly recommend Prue's place.
