The flat was BEAUTIFUL, and the terrace really big and warm. Overall the apartment itself is fantastic. The location was good, but not amazing- you're about 30-40 minutes away from all the center - Coliseum, forum, pantheon etc etc. by bus and subway.
The one thing that was slightly annoying was that the flat had these weird holes for the electricity that weren't the normal European ones: the ones on the flat need a plug with 3 metal sticks to work. The flat had one converter in the kitchen that I had to unplug and put by my bed so I could charge my phone and my computer. Not a huuge problem but slightly inconvenient.
Other than that, Stefano was great. When I arrived, he greeted me and sat down with me and a map to show me all of the best places around. Thanks Stefano!
