The host was very nice, she gave us a lot of tips regarding sightseeing, places where we could have food, do shopping etc. Additionally, on new year's eve, we found Prosecco and Pandoro in our room.
At Dandi Domus you get the room as seen in the picture with private bathroom. The location is really good, right next to the metro, 10 min walk to the Colosseum and 5 min walk to the main station. No kitchen but you get a voucher to have breakfast (a coffee and a croissant) at a local bar (cafe').
The only downside is that it's a bit loud. You can hear what is going on in the corridor and in the other rooms, also the small fridge in the room is a bit loud.
Apart this the stay was very pleasant.
