This appartment was awesome !
First, the place itself is ideal : you can do everything on foot, it is right next to the Spanish steps and not far from the historical center. The Colosseo and Forums are at 20-25 mn on foot, and finally, it is close to a metro stop which is always useful for the trips between Termini and the appartment.
The appartment itself is flawless, the kitchen is complete, you have one big bedroom and a clean bathroom. The noise from the street was pretty OK, except when Italy scored (but it won't happen everyday !).
Finally, Matteo was a really nice host, he has a lot of different addresses and tips to avoid ending in tourist traps and discover the marvels of Rome
Overall, a fantastic experience in Rome thanks to this appartment, and especially thanks to its owner Matteo.
