We stayed in Valentina's apartment for 7 days and when leaving the apartment, I almost felt like I was leaving my home. The apartment is comfortable, very spacious and fully equipped with everything you might need. It's situated right in the heart of the historical centre, pizzerias and restaurants all around the neighbourhood. The metro station Dante is 5-6 minutes walking distance from the apartment, though I recommend that you take a map from the information desk on piazza Gesu (2 minutes by foot from the apartment). The central station is on 4 stops with the metro, so this makes it very convenient to use the metro if you want to travel around in the region.
I didn't get the chance to meet with Valentina, but we were greeted by her brother Marco, who was kind enough to carry our suitcases up to the 5th floor upon our arrival. Marco helped us with ordering a taxi at 5:45am from the apartment to the central station by calling from the previous night and he was also kind enough to call a taxi once more when we were leaving the apartment. He was always answering promptly to any calls or messages that we would leave to him.
I truly recommend this listing to anyone, it is not to be missed.
