The nice and clean flat looks like on the pictures. It is tall, more like a Bed&Breadfast hostel instead of a private apartment. The kitchen is too small for 10 people though.
You have to pay the city tax which is 3,50€ per day per person in cash to Paola. That was a bad surprise for us at the arrival. It was not clear in the decription.
Anyhow, we enjoyed our stay in Rome very much and I recommand this flat.
