Really cool place, slightly smaller and darker than what the pics made it seem like to me, but not crazy.
Old building built on top of site of Theater of Pompey.
Campo de Fiori is a really nice area with plenty to do. Only down side was Friday and Saturday night it was very loud (people and music) until about midnight.
Honestly best part are all of Fede's recommendations. We tried a few different places from his recommendation and all were outstanding.
He also communicated very well with us in terms of check in and daily questions.
