The apartment is great. It is small but enough for 2 people. Is close to the centre (10 minutes walking to the Duomo). Clean, cosy and very quiet.
The only problem i found is that there is no a sofa, so is a little uncorfortable if you wanna rest for a while. There are chairs or the bed (and a small folding bed used as a small sofa for one person).
We didn't saw Raffaela, but she left everything ready for our check in and she was answering all our questions very quick. She even left us a bottle of wine, and some goods for breakfast.
