Very friendly and nice host. Answered really quick! Flat was good, clean and in quiet place, nice view from balkony. I came with car that's why this flat was good choice because it had free parking and was not so expensive.
For people who want to visit Rome and have no car (or don't want to ise it like me): you will spend at least 45 mins till city center. It's only possible using bus + metro and this bus is often late. Might be even 20 mins of waiting. It would be faster using a car, but I didn't want to use mine, because there's crazy traffic, a lot of jams, you will not find parking space in the city center and someone might scratch it during the day.
