I chose Villa Ada as first place on this list because I used to go there a lot with my family when I was a kid. Not to mention, I used to hang out a lot there when I was a teenager.
Villa Ada is one of the largest parks in Rome and it’s located in the Trieste-Salario neighborhood, in the northern part of the city. It was home to the Italian royal family’s residence, La Palazzina Reale. In particular, the Savoy family lived there from 1872 to 1878.
Also, king Vittorio Emanuele III and his family used to live there during the first half of the XX century — form 1904 to 1946.
