Me and my girlfriend stayed at Riccardo's apartment for three days. We didn't meet him but his father was very nice and welcoming to us when we met him.
The apartment is very nice, comfortable and well furnished. The location is in a small side street just behind the famous Politeama Garibaldi theater and is perfect for exploring the central area of the city.
Wifi was almost not workin while we were there, we messaged Riccardo about it and he sayd they were experiencing some problems and had to speak with the service provider.
