Casa Winkler was a lovely spacious apartment, very conveniently located in central Rome, just a short walk from the Vatican. (We used the Bus Shuttle service to/from the airport (Fiumicino) which dropped us about 300 metres from the apartment.)
Luigi was a very pleasant host who arrived at the apartment to welcome us. His father was there too who helped us with all of the tourist tax aspects of the trip.
The apartment was perfect for us, having all of the amenities listed including the all essential air conditioning. It was clean and well presented.
We were able to travel to the main tourist attractions using either the metro, or by foot. Nothing was too far away, and the delightful street restaurant to the right hand side of the apartment served excellent food.
A great stay in Rome, and we would definitely return to Luigi's apartment.
