Arianna was super nice and communicativ. She gave us good recommendations in the neighbourhood and was always reachable for questions. The flat is located in a calm area on the Metro Line A. You can find basic stuff in the supermarket 5 min away. There are also few restaurants. The Area is calm which we needed so much after sightseeing the entire day. Arianna recommend us two Restaurants and they were really good.
The Apartment by itself is exactly like on the pictures. You won't miss anything. Bed was comfortable and big enough for two. Shower is small, but everything is clean and works. Kitchen full equipped and with Gas stove which it's great, if y work as a chef. ;)
So, in total we had a perfect stay and would always coming back.
