This is a great apartment in a great location. Two large bedrooms, a living room with pull-out couch, and a kitchen with fridge and stove (there's a second fridge in one of the rooms). The apartment is clean, well-maintained, has great modern windows with heavy blinds to keep out the light and the heat of the day. We closed all windows and blinds when we were out and the air conditioning was more than strong enough to keep the apartment perfectly cool even in the August 30º+ heat. There is an elevator/lift that works very well.
The location is outstanding. St. Peter's Basilica is only 5 minutes walk, Castel Sant'Angelo perhaps a couple of minutes more, Piazza Navona and the Pantheon 20-25 minutes. Extremely walkable. The street next door has many restaurants, shops and gelato spots. Even these close restaurants can have great value and good food.
Check-in was very good. They were happy to have us come by the apartment as soon as our flight landed to drop our bags and get our keys. We got to the apartment around 1pm, even though check-in wasn't until 3, and we were able to leave and walk around the city.
Highly recommended Airbnb rental — if I return to Rome, I'd happily book here again.
