We had a great stay in Guiseppe's apartment. The reception was very friendly and flexible (we arrived later than expected). The apartment is well equipped and there was enough space for our group of five persons. The apartment was clean and the beds were very good. Thanks to the airconditioning it was not too hot during our stay in mid-Summer.
The best element is probably its situation. Just two minutes walk from the Pantheon and therefore right in the middle of the 'historic centre'.
I would recommend this apartment to anyone.
