I highly recommend this place. The building itself is SO historic, located in the windy old streets, yet really close to great restaurants and coffee shops. The pictures are accurate, but like someone else mentioned they don't really show how spacious it is.
David has added really interesting modern conveniences, such as the bathroom fixtures and the kitchen. There is AC in the bedroom, and plenty of fans for the other rooms for warm weather.
Checking in and out is via lockbox, directions to the flat are excellent, and there is plenty of information about sightseeing attractions. All around, it's just wonderful.
Probably my favorite place to stay ever :)
