We stayed for 6 days at Federico’s place during Xmas time. The place is great, convenient location, we only used metro a couple of times, otherwise just walking to the city center. Flat is spacious for 4 people, no issues whatsoever. All the amenities were there. The street might be busy, but it didn’t bother us much.
As well, the communication was very fast and always helpful.
Totally recommend this stay!
