Frank is a very friendly bloke and check-in was seamless.
Property is mostly as described with a very nice kitchen space, but we were a bit disappointed by the sleeping arrangements - the description did mention one bed was a "small double" but we found it impractical and uncomfortable for two people (both over 6ft). The other option is a sofa bed. Larger but if you are staying for more than a couple of nights and care about comfy beds neither of these are great.
The shower was also very small - again slightly impractical for anyone big/tall. The gaol cell doors are quite funky but be aware they provide little soundproofing if you are awkward about that sort of thing.
Lastly Frank's space downstairs appears to be a music studio of sorts. Much to our surprise this space was used regularly even with guests staying with singing and guitar being clearly audible upstairs. During our stay music was played until 11.15pm on a school night which seemed a bit off if you are Airbnb'ing the space directly above.
