For 56 Euro we got an excellent air-conditioned room with new bathrom fittings, high ceiling, and separated bedroom without prior booking. 24 hour reception helped us a lot, since it was 11PM and many value hotels were just closed. The location is also just 5-10 min. from all central sites.
For this price we also got a nice breakfast for two in a quite dining room. The only negative side is a distinct hint that the room wasn't always used as non-smoking.
