We had an amazing stay at Serena's flat. The flat is beautifully decorated, extremely clean and very well located (near the Vatican area, close to a tube station and to very convenient bus stops, with easy access to the airport). We were a group of 8 adults and one child and we all feel like at home and very comfortable. All rooms are spacious.
Serena has been very reactive and helpful as well as Gerarda and her husband during our stay.
We would definitely recommend the flat to any group that would like to have a pleasant and classy stay in Rome.
