Valerio was a great host and was easy to reach by phone, he even picked us up from the airport for a good price!
As for the apartment itself, it is in a very nice area and is walking distance to all the important piazzas. The jacuzzi tub was great and worked perfectly, and the bedroom with the big bed was very comfortable and air-conditioned.
The only downside about the place is the layout. The second bedroom is actually the reception in the apartment and has 2 single beds. So you directly walk into this room from the front door, then you have to walk through the kitchen and through the big room to get to the bathroom. So I wouldn't recommend the place for more than 2 people unless you're comfortable walking into each other's private spaces. Other than that it's perfect :) Thank you again Valerio!
