Fantastic place, fantastic location and fantastic host. 5 stars.
I travelled to Rome with two friends for 3 days and Sylvia's place was perfect. Great location, as it's a short walk from the train station and in the perfect spot for sightseeing activities. The apartment is very clean, stylish and comfortable. And Sylvia was even kind enough to leave us coffee and biscuits for the mornings. There's even a nice tv as well, which we used at night at the end of one of our days to watch a documentary.
We ended up needing to stay an extra day than what we originally booked, and it was no trouble at all arranging this with Silvia. Thankfully that extra day was available, and she was quick to communicate with us.
