Very nice hotel, loved their chic style and perfect location in the center of historical Rome. Walking distance of 15 min to the Vatican, 5 min to Piazza Navona. Colosseum, Palatino Hill were 40-50 min away. We walked by GPS to Palatino Hill and had a wonderful experience of Rome (although we did an unplanned detour). Dreamy narrow streets with cafes, bars and restaurants just outside the door.
Our room (with balcony) was at 5th floor with no elevator, but if you're in general good health this should be no problem. But it is annoying when you bring your luggage or forget something... Bathrooms were very delicate. Duvet cover was not, but it was OK. Balcony was adorable but it might have looked better/cleaner in summer time (this was november).
Generally a very good experience. Nice personell, chic interior, possibility to microwave + eat food in a small kitchen area, and make a cup of Nespresso before you head out for your eventful day. I'd recommend this hotel to anyone visiting Rome for the cafes, the history and the cobblestone experience... :)
