We really enjoyed our week's long stay in Loris apartment, it was a perfect fit for our four persons family (2 adults, 2 children).
The location is great - close to the metro and Vatican, so it was very easy for us to get around and reach various places in Rome. Grocery, various shops and restaurants are within walking distance.
The place was clean and very well equipped - we even used the washing machine (which we didn't plan), air-condition is available (which we did not need to use in April). The apartment is also relatively quiet as the windows are facing a small side street.
Loris and his sister were helpful as well as easy to reach and very responsive, the check-in and check-out were smooth.
Overall a great value - I would recommend it for stays in Rome and would book it during our next trip.
