Simone was an excellent host for our trip to Rome. He was very responsive during booking and prior to our trip. He was upfront about all the city taxes and charges for a late check-in so we were not surprised when we arrived. He even helped us set up seamless transportation to and from the airport for the same price as a regular cab.
Simone's flat was in an amazing central location for everything we wanted to do. We could walk to the typical tourist (and non tourist) attractions all over the city with plenty of restaurants and shops downstairs. The flat was clean and comfortable (although we didn't spend a bunch of time there).
Two things to note. The head clearance in the bathroom is pretty low, and you will not be able to stand upright if you are over 6'-0" tall. I am just under 6'-0" so it was tight, but fine. Also, the flat requires climbing stairs for access and within the flat. If you have trouble with stairs then I would consider other options. We didn't have any problems with either item, but as an honest reviewer I think it is good to mention.
Overall a wonderful place and amazing experience for us! I would highly recommend staying here and would stay here again.
