Sergio is a great host! Over and above the clean and well appointed space he also provided us with detailed maps of the immediate area and Rome's main attractions, restaurant/bar/gelateria recommendations, and even arranged our transport back to the airport at a discounted rate. The room and common areas are quaint and stylish and we really weren't lacking anything during our stay.
It's worth noting that this is a shared space and other guests can sometimes be heard at night, but with the exception of some loud snoring on one occasion this was not a problem for us. While the space is very close to Vatican City, other attractions are a healthy walk away, so be sure to bring good shoes. There's lots to see and discover in Rome, and in our experience walking was the best way to see it all!
Thank you Sergio - we will be back!
