Our stay at this apartment was wonderful! The apartment was exactly as pictured, and very clean when we checked-in. At night, the building and room were very quiet. The windows look out onto the main road but you could hardly hear any street noise at all. The apartment is not particularly close to many of the historic sites (colosseum, pantheon, etc), however several bus lines run right in front of the apartment and we never had to wait more than a few minutes! The metro is probably a 20minute walk (or short bus ride away!). The apartment is so close to Vatican City, and you can see the basilica dome right from the window!
We highly recommend staying at this apartment, and if we return to Rome we will definitely check if Piero’s apartment is available first!
