Alessandro and his son Camillo are very kind and helpful. At the check in Camillo explained the main things about the apartment in a kind and polite manner. We had some trouble with the wifi (although I don't think its common) and Alessandro came twice to the apartment to make it work again. When it didn't, he got a pocket modem to keep us through the night until he fixed the other one!
The apartment is well located, close to all the main attractions of the city and also the train station. We did everything by foot. Still, the apartment is not on the center or in a crowded street, so its really quiet at night, which is good for sleep. The walls are a bit thin, so we could hear the neighbours fighting sometimes (haha), but nothing that bothered us that much.
As for the apartment itself, it is comfortable for two people. The shower is hot and strong, which we loved. It could be a little bit more clean, specially the kitchen, I think someone spilled olive oil on the knives and didn't see it. But all together, it's a good apartment if you're looking for a good location and a good price (:
