Costanza's apartment is in a perfect location. We honestly walked everywhere and visited all the sights! The only time we used a taxi/train was to and from the airport! It is situated on a cosy sqaure, right by the river. There are beautiful restaurants right on your doorstep. You are just far enough away to escape the hustle and bustle of the tourist areas (but still all easily walk-able), you can mingle with the locals in the restaurants/shops surrounding the apartment.
Costanza's apartment is super clean and so lovely, there was a bottle of wine and snacks waiting for us upon arrival which was a great touch! Costanza provided us with a map and an abundance of helpful info and recommendations for restaurants/bakeries/coffee shops/things to do. It's great to have a local inhabitants recommendation!
Honestly could not recommend more, thank you so much Costanza.
