The appartment looks exactly as described and shown in the photos. We were a group of 6 friends, the place absolutely fulfilled our expectation. It's located 5 minuites walking from the Castel Sant'Angelo, and 10 minuites from Piazza di Spagna - in the very centre of Rome, just a block from the Tiber, without a need to use public transport. Marco ordered transport from and to the airport for us for a very reasonable price. He awaited us in front of the house on time, showed us round the appartment, explained how to use various devices, and gave us 2 sets of keys. We were only requested to take out the rubbish before checking out. We had enough bed linens (and extra blankets if we were cold), and 3 towels per person. Both bathrooms worked well even if used at the same time. The only thing I would suggest to improve is to offer more space for clothes in the bedroom with separate beds. The wardrobe is too small and full of baby beds and such stuff.
I recommend to stay in that place, it's perfect for groups of friends or families.
