Silvias apartment is probably the most price worthy option you can find in central Rome for two persons. The location is the main attraction with this apartment. It is within walking distance to the Vatican, Trastevere, Monti and a lot of the major historic sites in central Rome.
Silvia's apartment was clean and organized. Nothing luxurious - but i can't imagine anyone going to Rome to sit in the apartment. Communications with Silvia was easy and she always responded within minutes and she was waiting outside the apartment with the key when we got there.
I have nothing bad to say about this place when you compare price and location to other close by options. Would definitely get in touch with Silvia if I was to return to Rome.
