Perfect location and great and lovely host! The only downside is that the apartment in real life is much, much smaller and narrower than you might think from the pics. We stayed for two weeks and I wouldn't recommend it for longer stays. For a couple of days it sure is nice and sweet! Also, it was not possible to lock the door from the outside. This definitely should be taken care of. We also realized that, when the door leading to the attic, where the bedroom is, gets shut you can't open it again from one side. We put something in between to prevent this from happening.
Again, location is perfect, you are in the middle of the old town, very quiet as there are no cars, very original, tourist attractions close by, great to walk around.
