The location of this place is great, it is only a 6 min walk to the Vatican museum, the Metro and multiple bus stops are only 2 mins away, the apartment is a good size and well equipped with comfortable beds, there is NO free parking on the premises, it is free street parking but the host helped us find a spot only a block away, we did have 2 negative impacts on our stay, the internet was much slower than what we are used to and the shower is very small, a large person would not fit in.
There are lots of restaurants close by and 2.5 blocks away (turn right when you leave the building) is a great local market where you can pick up fresh food from a large variety of food purveyors, even wine you can taste then purchase at wholesale rate by the litre, we would stay here again.
