I had a fantastic stay at Silvia's place. Silvia was a great host and very accessible. The location is very central with many of the key attractions within easy walking distance. The Trevi fountain is about two minutes away. The room and facilities were excellent and as described. There is a restaurant right at the entrance of the apartment so there's always lots of people around. There were noises from the street but it didn't really bother me.
Overall, my stay at Silvia's apartment made my Rome experience that extra bit better. I'd definitely stay again the next time I'm in town.
