I had a pleasant stay in Claudia's house, I stayed there during 5 nights for work. The decorations and art in the house are amazing and it looks like you're walking through a museum. I am a light sleeper and for me the house is too noisy due to the two roads on both sides of the house. I also think this house can be best used with a car. Walking to the airport is definitely possible (10min), but the last bit is without a sidewalk (so on the road with fast driving Italian cars) or as I did, through the grass/mud/leaves/trees.
There are three bedrooms, and for me only one mattress was soft enough, the rest is quite firm. I think this place is perfect for 1 or 2 days when you have to be close to the airport.
