This is an ideal apartment for a city break - it's well located within a 10 minute walk from the Vatican, close to the San Pietro train station and right next to a number of bus stops that take you straight into the centre. There's a small supermarket right next door. The area is not as touristy as the centre, so prices in restaurants and bars aren't too inflated but I was surprised that so many people spoke some English. The apartment itself is clean, nicely furnished and with air con (a godsend in summer!).
Britta was a really helpful host; when she checked us in, she told us about the different bus numbers and routes, the best way to walk into town and suggested some good places to eat and drink. I would highly recommend this apartment for a sightseeing break!
