Frank's jail is refreshingly different to other Airbnb's I've stayed at. It has so much character in a really great part of town. If you're not afraid of trying something different to typical built-up city centres try somewhere like Montpelier because it is refreshing. Surrounded by amazing Cafes and independent shops (The Bristolian and The Crafty Egg were my favourites).
Frank is a great host and always replies straight away!
