After booking Gianluca contacted me right away. He communicates fast, kind and with perfect service. When I was out of coffee, he showed me right away where I could find more. When I wanted a blanket, he brought me one within a couple of hours. When I had a question, he answered within a couple minutes. I felt very welcome, he is an amazing (and hot ;) ) host!
The apartment is really in the center of Rome. Everything is close by and I did not use the metro once. You can walk to the north, Trastavere, Vatican and the train station all within an hour. It's a comfortable spot, with amazing ceilings, a nice balcony, in the busy city center.
I arrived really late, so it was perfect that there is an easy to use lockbox for the key. I did not know the kitchen was shared, but the girls in the other room were really nice and you won't be home much anyway. I am someone who loves cooking, but I haven't cooked once in Rome. Really unnecessary and you have your own fridge anyway. Good coffee in the kitchen too!
My advice: if you like to be in the city center, enjoy an old fashioned apartment, and don't mind sometimes meeting the other roommates in the kitchen, this is the place to go! I felt very much at home in a city I had never been in.
