This apartment is as lovely as it seems and the location is excellent for exploring the old city on foot.
Just one important thing: Like many apartments in old buildings in European cities, this one has sewage drainage issues. Do the following right away to avoid very unpleasant odor in bathroom: 1. take a small towel and place it on top of the shower drain, wet it and keep it there when not using the shower. 2. Close the bathroom sink drain when not in use and 3. put something you can later pull out easily (folded paper towel for example) in the bathroom sink vent.
The hosts were right there for us whenever we had a question. This place is very worth it! Enjoy!
