The Pool at Hotel Principe Di Savoia

"The sheer size of this 401-room behemoth will not suit all, but it does guarantee top-class facilities, including a full-featured spa with indoor pool, a decent modern Italian restaurant, and two bars"

"As well as such glitzy touches, this classic luxury hotel offers superb service and excellent facilities, including a rooftop fitness centre and pool with glorious views over the city"

"The Mosaic rooms (named for the glass mosaic panels in their ample bathrooms) are even larger, and the three-bedroom Presidential Suite features its own marble pool"

"The top-floor fitness and spa club with beauty centre offers sauna, Jacuzzi and indoor pool"

"Frank Sinatra, Robert De Niro and Madonna have all stayed in the presidential suite, which has its own pool"
