The apartment is located only minutes walking from the cathedral, so you cannot beat the amazing location!
It is a very charming studio, tastefully decorated, and the host Bettina is really good and quick at responding and fixing any issues. I encountered some cleaning issues on the first night, and this was taken care of the next day, as soon as I mentioned it. I even received a nice bottle of wine as a present for the inconvenience!
The double AC works great, there are window blinds for the night, and the rooftop offers a great relaxing space to eat breakfast or have a glass of wine at night.
The only little down sides, would be the strict check out time (it will cost you an extra 30 euros to extend the check out time), and the lack of elevator.

Aside from that, I can only recommend the space to anyone. It is one of the best space I have stayed at on Airbnb, you will not be disappointed!
