The photo's are very, very optimistic. Shower is absolutely tiny (and broken), with no space to put your stuff. Same for kitchen and bedroom. It's also not the cleanest place I've visited.
The location is great, but very loud at night. Sounds from people and traffic outside go on until 2' midnight, so if you are a light sleeper, then bring some earplugs :-)
The description says it has space for 4 persons, but trust me: it doesn't.
In our stay we have seen places with better value for money. Just go slightly outside the old town! Everything is in walking distance anyway.
