Stefano and his girlfriend were very nice and helpfull. They had arranged us the private driver (only 2€ more than the regular taxi-fare) to come from and go back to the airport.
They also gave us some great advice on restaurants, bars and attractions.
The apartment is very clean and consistent with the description and photos.
Its location could not have been better. You can do everything by feet, which is very appreciable. We highly recommend it.
