We haven't met Sarah but she was available during our stay and we communicated very easily via phone. Emanuela welcomed us and showed us all the facilities.
Fortunately, the house is located away from de touristic mess but it's very easy to reach all the transports. The room was clean and cosy and the area is very silent therefore perfect to rest after a long day walking around. However, if you have a sensitive back as I do the mattress may get a little uncomfortable as you can feel the springs. This was an issue for me but not for my boyfriend so it really depends how sensitive you are.
There was complementary tea, coffee and toasts available in the kitchen but we had our breakfasts in this amazing cafe nearby. The owner is the sweetest person and the cappuccinos and croissants are the best! Overall was a good experience and we can recommend Sarah's place.
