Like everyone says, Enrico is a great host! The appartment is small but clean and has everything you need when you're on a city trip. Enrico provided us with fresh water, breakfast and welcomed us with a bottle of wine after pickup us up at Montesanto metro station. Even on the day of our departure, when we had left our luggage with them, they put an extra bottle of water on top op our suitcases: very sweet.
Before our arrival he told us about public transport and cabs: all very helpful and accurate.
And in case you didn't prepare your trip: there is enough information in the appartment. It's like a little tourist information centre in there! Great stay.
