We just spent a week at Federico's apartment and really enjoyed our stay. We really appreciate that Federico was very flexible with the early check-in and welcomed us personally into the apartment.
The location is right in the center and it worked great for us to be able to come up to the apt a few times a day to rest (especially during the heatwave) and go out and enjoy the city again.
Just around the corner from the apt there is trattoria Da Tonino where we loved to have our lunch almost every day, they're very friendly and offer home made delicious food.
The apartment is on the first floor with two easy flights of stairs above the ground; the place was quite spacious for the two of us, but might be a bit tight for three or more people. It was very clean and well equipped, we were especially impressed with the modern front door lock system which made us feel completely safe and leave our valuables inside without any hesitation.
The apartment has two strong AC units one in each room which was real relief for us with the 36' outside. The shower is great with strong water pressure and the bed is nice and comfortable.
Overall, it is a very nice place to stay and enjoy the city.
