Andrea is not only super responsive, but he's also very welcoming and helpful. My husband and I stayed two nights in his cozy apartment. The place was well-appointed. We typically grade our lodging based on the following amenities:
1) wifi
2) comfy bed/sheets
3) decent shower with hot water/sufficient water pressure, and
4) good location.

For the price, we were pleased with Andrea's place. The apartment felt very authentic. Please note that the unit is on the top floor (5th?), so be prepared to lug your stuff.

Also, the walk downtown is about 20'-- not terrible, but after four days walking all over Florence, we were thankful to use the bus in Bologna. This worked well for us, but mostly because we had Google Maps Transit at our fingertips to tell us where the bus was and where we needed to get off... (We didn't see many bus maps at the stops downtown.)

Finally, if you want food recommendations, be sure to ask Andrea: his girlfriend writes a food blog!

Thanks Andrea for a comfortable stay!
