We came for a week with 2 children aged 11 and 9. The appartment is a lovely place and well located: very central and a lots of shops and places to eat in the area.
Our evening strolls took us every night around the Vatican and there are many ice-cream shops everywhere and round the corner. A lovely relaxed athmosphere.
The appartement is spacious enough for a family of 4 and the rooms were both big with ample storage. The only down point was the bathroom smell ( lucky we came in October when it is not too hot) and the toilet seat remains unfixed.
Baring this in mind, I would recommand the place for its amazing location and the spacious rooms. Special mention to the lovely lady who works on the ground floor and helped us with booking a taxi despite our basic Italian and her basic English.
