Frank's place is unique and in a really interesting area - lots of independent restaurants, cafes and bars in the local area. We managed to get around everywhere on foot from there. Frank was also very responsive in the run up to our stay.
The only negative is that the peacefulness of the area must have changed since the other reviewers stayed at The Old Gaol. There was loud music late at night, so it really depends what you're headed to Bristol for.
