My family (wife and two teenage daughters) stayed here for 4 nights in June. The process to book was very seamless. Lorenzo responded very timely to all my questions prior to booking. Lorenzo even set up a car service to pick us up from the airport which made our transit to the apartment very easy. The check in was easy.
We all liked the location of the apartment. When you step out, there are plenty of restaurants at bars within steps. Trastevere is known for it's nightlife, so if that's what you like, then the location is perfect. Having said that, the apartment was very quiet with all the windows closed. The location was good in that all the major sites are walkable. The apartment looked just like it did in the photos.
The apartment was very clean. Our family liked that there was water waiting for us when we checked in as well as a fridge to keep food and other drinks cold. The air conditioning worked very well in both rooms as well as the TV setup for those moments when we wanted to relax. We enjoyed one of the nights up on the private deck upstairs. One amenity which would be a bonus would be a washing machine to do a bit of laundry, especially when Rome is part of a longer trip.
I would definitely consider this is as a top option when visiting Rome again and would recommend to friends.
