We had a really nice stay in Sonia's apartment and in Rome in general. Her boyfriend welcomed us when we arrived after they had given us good instruction on how to get there, which was really easy.
We felt very welcome and loved the apartment. The neighbourhood was quite and we found a really nice restaurant in the same street as the apartment. We did a lot of walking the week we where there and next time we go to Rome we would probably stay closer to Trastevere but this time around we were going to a conference and this apartment was very close to that so it was perfect. We never met Sonia though but she is most likely as nice as her boyfriend.
