Great experience - there is a reason they have such a high rating! My best experience with airbnb in Europe - Signore Remo and Signora Marissa were great hosts and they quickly responded to my messages. Though they did not speak much English, we were able to communicate well. They were outside the suite when we arrived and gave us a map and showed us major sites to go to and how to get around.
The location was perfect - it was a few blocks from the Colosseum, close to the subway station, and all major sites are nearby. There is a cafe right next to the location and I believe they include breakfast (though I left too early the next morning to have any).
The suite had everything we needed and everything was freshly cleaned for our arrival. The double bed was comfortable, the bathroom and shower were not large but were actually the best we encountered in all our airbnb stays in Europe, and they provided a sink with drinking water, a fridge, and a coffee / tea station. The A/C and blow dryer were also great.
I highly recommend this location and definitely plan on staying here during my next stay if it's available. It's a great value and a quality experience.
