Staying at Maria's place was great. The flat was clean and cute. Having a kitchen was a big plus when we were not feeling like going out to eat.
The location is AMAZING, it's right in the center of the old town ! It can be a little tricky to fing a parking spot depending on when you arrive but then you let the car where it is and go by foot to visit anything or to go to the restaurant.
The only mini negative point is that you ear very much the neighbours upstairs... so make sure to have earplugs packed in case the people upstairs are as loud as the one when we were there...
