We were a group of 6 (4 adults and 2 children) who stayed in Federico's apartment for 3 nights mid April, and we had a wonderful stay.
Before arriving we were in contact with Federico a couple of times, and he always answered very prompt, same was the case during our stay when he arranged a car to pick us up.
When we came to the apartment on the first day the lovely lady, who welcomed us, gave us very good local information about supermarkets, bakery, what to see etc. It gave us a valuable knowledge which we used several times during our stay.
The apartment is exactly as shown at the pictures, nice an clean, and the location was excellent. We were very close to more or less everything in the city center, and even traveling with children we managed to see all the things to see and as we expected it was all in walking distance.
We would definitely recommend this apartment and would love to come back again.
