Apartment is near Roma Termini & airport bus station, you can walk to there within 10 minutes and go to any historic attractions by walking distance except Vatican & St. Angelo castle which can take the metro by few station.
Gianluca & her husband are very nice, they waited us in the gate of the building and prepare many snacks, foods & drinks for breakfast & supper.
The house is clean and very chic decoration, there are 4 rooms with private bathroom and suitable for 11 people. The only criticism is the dinning area & kitchen is basic, not big.
Anyway, I will stay again when I visit Rome.
