We (3 kids, my wife, myself and my mother in law) stayed for 3 nights in the apartment.
The apartment was as we expected it to be according to the description.
Mario handled the check in a very efficient way (it took not more than 5 minutes).
The area around the apartment is not touristic. I would say that normal people live in the area. You find a supermarket, ice cream shop, places to drink a coffee ... in a couple of minutes by foot.
Overall we were very happy with the apartment and Mario.
