Mirko was very friendly and easy to communicate with. He provided great local tips and booked my airport transfer for me when I was having issues finding someone. The apartment is really well located in Trastevere, close to the restaurant/bar area but in a lovely quieter street. It is 5 minutes walk from Ponte Sisto so the Centro Storico is easily accessible by foot, as are buses trams and taxi ranks. The apartment was in an old building but very nicely renovated with good facilities. The "hidden balcony" was also a lovely space to relax. I definitely recommend both Mirko as a host and this apartment.
