We stayed in this lovely Airbnb for three nights. The whole flat was clean, the bathroom is small but modern and the rest is very spacious. We had everything we needed (working AC, closet with hangers, good fridge, big mirror in the hallway and so on). Keep in mind that this apartment is on the third floor without an elevator.
The location is top notch. The Airbnb is in a litte side street right next to the campo fiori. You can walk to the piazza navona in like 5 minutes, Pantheon in about 10 minutes and even the vatican or colosseum is within a 20-25 minute walk reachable. We never used the bus or tram during our stay.
The check-in was easy and uncomplicated. Fortunately we could check in a few hours before the normal 1400-check-in-time. Emiliano, who did the check-in, came on time to the apartment and gave us an introduction. He was very nice and gave us some good recommendations (restaurants, bars, lovely places, etc.) for Rome. He is helpful as well and always available via Whatsapp.
Overall i would highly recommend this Airbnb!
P.S.: A recommendation by ourself: You have to go the the "Caffè Peru". It is nearby in a parallel street. Great for a little breakfast (Latte/Cappucino/Espresso like 1,20€, delicious Tramezzini, Sandwiches and ther bakey products). It was very authentic and we were the only tourists there. You can also have longdrinks and cocktails there in the afternoon!
