Hot tub and location really are the saving grace of this accomodation. Check-in was also straightforward and communication was always quick and detailed.
Downsides: extremely noisy street, especially on weekends, the flat decor is rather outdated and not particularly welcoming or comfortable. The bathtub is so narrow you risk falling or slipping and some parts of the flat have been 'repaired' using duct tape and certain spaces are just full of junk and things left behind by previous guests.
If you can ignore these points then it's a good enough stay - the location is excellent, I'll say again.
