My friend and I had a nice stay at Francesco's place! There was a lot to like, but also some things you should know if you're considering staying here.
To start with the good: it's in a nice central location, and the view from the balcony is spectacular. We also thought it was a great value--it's a whole lot of space for the price, especially when you're used to traveling to more expensive cities. Francesco was very communicative, and he helped accommodate an earlier check-in so we wouldn't have to carry around our bags all day. In addition, the bed was very large and comfortable, and he gave us all the necessary materials (e.g., towels) for a comfortable stay.
However, the wifi was disappointing, as we had been planning on streaming some video during our stay (there was an important football game I was intending to watch, and my friend was also hoping to watch a little Netflix while relaxing). It's more of a mobile hotspot than an actual router: the connection itself is quite good, but Francesco specifically tells you it's for things like checking emails--NOT for streaming video. Also, the shower was not ideal, as the water heater takes up quite a bit of space inside the shower, and there's no holder for the nozzle (so be prepared to use one hand at all times to hold the water on yourself). In addition, the neighborhood got pretty loud at night--especially on the weekend. And, if you're a less mobile traveler, you should know that there are some unusually steep steps leading up to his apartment.
All in all, we had a very enjoyable stay. I'd fully recommend his place, as long as you're aware of and comfortable with the issues I described.
