Stayed at Valerio’s apartment with my sisters for a long weekend in Rome and had a great time. The flat is very clean and stayed very cool despite the heat outside. The air con was also a great benefit! The flat is in a great location - you can see the colosseum as soon as you step outside. It’s also not far from other key sights. We walked everywhere while we were there. However, if you wanted to get the metro or train instead, these are also super close.
