There is no better place to stay if you plan on staying near the Colosseum. Literally steps away, and you can actually view it from you windows! There are wonderful restaurants with a few minutes walk, and a grocery store next door. You can grab a taxi outside or hit the Metro Colosseo in 5 minutes.
Wonderful apartment (we had 2 adults and 3 kids) with all the amenities. The apartment is clean, well furnished, and very liveable. We would absolutely stay here again when we are back in Rome. The only downside was that it was quite noisy at night, but, hey it’s Rome!
