The room was perfect for our week in Rome; big enough for two people, everything was spotless, the bed was really comfortable and the bathroom quite big. There were only 5 rooms, so the shared living room/kitchen was big enough and had everything we needed: tableware for eating some precooked food like sandwiches or salads, a fridge, a couple of tables, etc. The location of the apartment is great: a safe and calm neighbourhood with lots of restaurants, close to Vatican City, Castel Sant'Angelo and Piazza del Popolo and also near to Lepanto Metro Station and to the SIT Bus Shuttle stop, which is great to get from and to Fiumicino airport.
Luigi was very attentive, it was very easy to communicate with him and despite arriving before the check-in time and leaving after the check-out time he let us leave the luggage in the place.
And finally, thanks Luigi for the suggestions of the restaurants and gelaterie, we tried 3 of them and they were amazing!!! I would recommend Winkler Suites to any person or couple that want to visit Rome :)
