Location, location, location! This is where the apartment really wins. We stayed here three nights on our way to a walking tour in Umbria, and it was ideal for our purposes. It's a 10 minute walk from Termini station, Piazza Barberini is just down the road, and all the major sights are within reasonable waking distance. It's on the fourth floor of a stately 19th century palazzo, a bit tricky to find on first arrival, but once inside there's a quirky wooden lift to trundle up and down in.
The room is part of what seemed like a large apartment. The stylish 'breakfast room' shown in the photos is actually the entrance hall, which is used by the apartment's occupant Ana, who looks after the guests. Emanuele does not live there and we didn't meet him, but Ana was very helpful and welcoming. She does not speak English (nor French or German, which might have helped) and our Italian is limited, so communication was by gestures, pigeon Italian/English and laughter. She served us a simple breakfast on the balcony each morning.
The room is spacious, airy and clean, with a comfortable bed, ample storage and a nice en suite bathroom. It was lovely to have access to the balcony, although it is a sun trap in the afternoon and became too hot. There is no Wi-Fi.
Emanuele's communication with us before the trip was helpful and welcoming, and all in all the accommodation lived up to its billing. We'd go back.
