It's an excellent location for a tourist. 10 minutes to Roma Termini and 10 minutes to Colosseum. Metro is also nearby.
Giulia is an excellent host. She prepared everything to make our stay comfortable. Even olive oil and spices in the kitchen.
Things to beware - it's a 5th floor without a lift, and there's a pub on the street. With all the windows shut the noise is not too bad but it could be a problem with the windows open.
