Travelling to Rome in September to celebrate my mum's 80th birthday, she is fit as a fiddle and will have no problem walking around the city. No 1 destination for her is the Vatican and then of course all the other sights. Looking for a nice play to stay. There will be 3 of us so if we could all be in 1 room it would be a bonus but not a necessity. Any advice gratefully received, we will be there for 3 nights.
