The location is literally perfect. The place is one block off the main cross street and you can walk safely and quickly to the Colisseum, Pantheon, and infinite restaurants and shops.
The space itself is quiet, clean, and a nice balance of modern while maintaining the old downtown Rome vibe.
The only reason I did a 4 is we had trouble with hot water so, to be fair, I couldn't put 5 star. Even then, Cristina was wonderfully responsive and did all she could to help. I would happily stay again and I'm sure this one lost star from technical difficulties will quickly get lost in the sea of 5s, even mine when we surely return!
