The room was great. Very comfortable bed, pretty big bathroom with plush towels, a small refrigerator, A/C, a common area with couches etc. common area also has a microwave, tea, coffee and water. The night we came, the elevator was broken so we did have to climb about 40 stairs but there is an elevator generally.
Location is AWESOME with restaurants all around within minutes, a 10 min walk to the colosseum and most importantly if using the public transportation system. 4 min walk to the train station and two stops from the main hub (Termini station). You can take the train to/from the FCO airport. Cab ride to CIA airport is only €30 and you can use the mytaxi app to book. I had to catch a 4 am cab to CIA and was able to schedule it the night before.
Antonella is a wonderful host. Very responsive to questions and available at short notice. She not only guided us from the train station to the apartment but had one of her staff members come out to watch for us. She was available no matter when I sent her a message—for instance, at 10 pm asking for a taxi number. She responded right back.
We would absolutely stay here again.
