I stayed at Armando’s place for four nights and I enjoyed it a lot!
His place is located by Piazza Navona and is walking distance from almost every touristic attraction. Aside from that, there are several nice restaurants and some bars and cafés nearby his place.
He was a caring host and was very responsive. When I asked for his suggestion on restaurants in Rome, he provided me a list of nice restaurants and his own comments on each of them. And of course, I recommend him as a good host.
