Good located near the Vatican. Communication with Elvio was good and fast, also no problem speaking in English.
It is not really a BnB, just a flat with two bedrooms and we were unlucky that an entire family was in the other room (and common areas) during our stay, so it was pretty loud and not ideal but overall fine for a short trip and host was very accommodative.
It would be good to note that it is not parking on premises (as stated in the ad) but there is a free public parking place not far away and we managed to find a spot.
