Silvia is a great host, she waited for us when we arrived at the apartment even if our flight was delayed, and the communication with her was very easy.
The apartment is perfectly located, it couldn't be more central. It was very clean, and Silvia left a lot of treats for us (muffins/cakes/wine/milk/orange juice). The only detail that is not her fault but might be important for some people to know, is that the elevator stops between 2 floors. So you still have to do a half flight of stairs to go in the apartment (not wheelchair/buggy friendly).
Other than this, we were very happy there and would definitely recommend Silvia's apartment.
