We had a good experience in general. The flat is very centric and allows you to go walking everywhere. The building is very old and there is a strong smell at the entrance of the building that might affect sensible noses.
We went by car and we were told that there was no problem with parking the car on the street. At our arrival, the person that received us said that during that very week the windows of three different cars were crashed. We ended up using private parking (35eur/day). Bare this information in mind in case you are traveling by car.
