I went to Rome for work during a 1-month stay. I stayed at Simona 's flat the entire time and I have to say it was a lovely experience. The flat is small but is perfect for 1 person and has everything you need. Besides, it has a wonderful localization, just near St Peter's and just a few minutes from the city center by walk. I received my brother during a weekend and Simona provided every linen and towels. It is quiet and has a lovely balcony. It is on fourth floor without elevator but it was really good to exercise after all the pizza and pasta :) I absolutely recommend it!
Hope to come back and certainly stay again in this flat.
