I really enjoyed this place! Once we made it up the stairs (with luggage to stay in Europe for 3 weeks this was a feat...) we were very pleasantly surprised to be welcomed by gorgeous sights and smells from all the flowers in bloom. Her garden with flowers and trees were as lovely as the pictures.
The studio by appearance is basic, but it has everything you need. Definite benefits for us were the kitchen and washing machine. Wifi is a bit tricky. In the studio, it only works by the door and table and is best with the door open.
Location might be the only downside. She is very close to St. Peter's Basilica and the Vatican City, which was awesome. However, getting into the historic city center takes a little while, not because of distance but because of over-crowded buses (beware bus 64) and lots of traffic.
All in all, Silvia was a great host and very easy to communicate with. She has a notebook filled with the essentials, like how to get around the city, things to do, and most importantly where to eat. Definitely recommend the food around her house, especially Goose.
