What a great experience. The attention to detail was the main reason for writing this glowing review- as an example, we struggled mightily with jet lag on a previous trip to Europe from the US- because Marco installed automatic black-out window blinds, we were able to get perfect sleep exactly when we needed it and felt amazing two days SOONER than our last trip. With shorter trips to Italy where every day is planned for maximum experience, this one benefit is an example of Marco's commitment to excellence.
The location is incredible, 2 blocks from good food/local vibe, 2 blocks from the metro, and a ten minute or less walk to the Colosseum. I would recommend this Airbnb based on this factor alone, but the large spaces, multiple bathrooms, and cleanliness just took this experience to new heights.
