We booked our stay here based on the wonderful reviews, and am happy to say this is another!
The apartment was cosy and comfortable and had everything that we needed for our stay. The location, as others have said, was absolutely perfect - attractions and nightlife alike, everything we wanted was within walking distance.
Most of all, the communication was fantastic which made staying at the apartment absolutely stress-free.
If (hopefully "when") we come back to Rome, we would love to stay here again.
