It was Chiara, a friend of Maddalena, who welcomed us. She is a very polite, open and friendly person, she even picked us up at the train station due to heavy rain.
The flat is very cosy, although you don't have the entire apartment for yourself as you are living with two other apartment guests in the flat, but everyone has it's own bathroom and it is a good way to meet and connect with other people.
The flat is also very clean and easy to reach. From Trastevere Station it is a 5-7 min walk and you can get easily to the city center from there.
Unfortunately at our last evening there was a power breakdown in the whole building just after we came home, so we were out of any energy/power for about three hours, no possibility of any light source and as the flat is in the 8th floor we were kinda trapped.
But I think this doesn't happen very often, so it was just a case of bad luck.
Nevertheless we had a great time in amazing Rome and Maddalena's and Chiara's apartment is very nice, modern and absolutely good located!
