We stayed at Federico's apartment for 4 nights and we had a wonderful stay. The apartment was clean, really lovely and partly even nicer than portrayed in the pictures - the bath for example now has other walls and was probably renovated - it was really good to use. The water pressure was good, as well. The absulute highlight was the big terrace. It truly was great to sit out there. There is a building site in front of it right now, but there wasn't any noise. The surroundings was great, too, we can recommend the restaurant 'Romulus and Remus' (which isn't touristic at all and in a 10 minutes walking distance). In general you can almost walk everywhere from the apartment, if you don't mind a stroll; we even walked to the Spanish Steps in under an hour and there was a lot to see on the way. In general, we have nothing but positive feedback about the place and would definitely recommend staying there!
