Sylvia was perfect for us and most welcoming. On arrival, she provided a tart and was extremely helpful when we had baggage problems. Our accommodation was in a separate room in the garden that was very quiet and sunny during the day. The neighbourhood was good and it was only a short walk to the Vatican. Sylvia also provided a lot of useful information on restaurants in the area and when we tried them they were very good and not touristic. The "scala" to the apartment was significant and required some level of fitness but we had no problems with this.
All in all, our time at Sylvia's was excellent and we were able to come and go without problem.
Given the opportunity, we would love to stay at Sylvia's again.
