I have nothing to reproach, perhaps just a little to hear the subway underground and out toot ambulances and police, but it is not the fault of the hotel.
Excellent location a short walk from the Colosseum, nice hotel, clean, daily changed bedclothes / for my taste unnecessarily /, towels, soap and shampoo. In the bathroom large shower, toilet, hair dryer. Room is a bit small but that's enough for sleeping. Breakfast always the same, but tasty and fresh: scrambled eggs, toasted bacon, sausage, cheese, fruit, sweet cakes, yoghurts, muesli, tea, coffee, milk, juice. Lacked vegetables. Very nice lady, what served. In fine weather was breakfast on the terrace. We felt great there and it was amazing for us retreat after a long day in Rome. I recommend!
