Amazing stay! We were 3 persons staying at Federico's apartment for over a week and it was super comfortable. The apartment itself has 2 rooms and 2 baths and is fully equipped (good wifi, kitchen, laundry, dishwasher, ironing stand, umbrellas, etc.). It's on the top floor accessible by a cute lift as well as stairs and is in an elegant neighborhood. It's an easy 10-15 min walk to villa borghese and lots of shopping, and about a 20- 25 min walk to the historic center (pantheon, Piazza Navona, Trevi, etc.). We were also able to find parking easily on the street in front.
Federico was a great host, we were warmly welcomed with a Nutella torte and good suggestions for places to eat nearby :) I would highly recommend the apartment
