Certainly the highlight of staying at Catharine's apartment was the splendid view of St. Peter's Basilica...a stunning sight,especially at night.
Catharine herself was very hospitable and welcoming,presenting us with all sorts of information on transport,eating out,sights,shopping.A real bonus was the food in the fridge a bottle of wine,fresh croissants and buns delivered daily together with the unlimited supply of pure drinking and sparkling mineral water.
