Great location and a very cool flat. At first you might think it's noisy, as the street outside the living room is pretty busy, but once you close the windows and retreat to the bedroom (conveniently located at the other side of the flat, far from the street) you can really appreciate the peace and quiet.
There are great pizza/gelato pleaces nearby and you can walk to the main attractions without problem. A bus stop is located 3 minutes from the flat, from there you can get to lots of places from the Colosseum to Termini Station.
And let's not forget about Federico, who was the best host we have met, flexible, kind and knowledgable. Thank you for your hospitality!
