The apartment is really well situated in Trastevere. Historical center can be reached by 15mn walking, the Coliseum is 30mn away with tramway 3 and the Vatican is 30mn away from walking... We had a really nice stay, the terrasse is perfect for taking a breakfast or chilling at night after a big day of visiting.
The price/quality is really interesting, as you are situated in the Trastevere, with everything around ( Transportation and markets). We had a good time speaking with the host Gabriel, and learning more stories about Rome and Italy, he is a wonderful and wise person !
If you wish to visit Rome and discover it, this is a really nice place to stay !
