I have tripadvisored every hotel in and out of the city and now it's driving me mad!
Hotel Forum, Hotel Mozart and the one by the Pantheon are the hot contenders. About £150 or E200 max in August.
Problem is I know it will be hot but I can't work out best location so that you get maximum interest for minimum walking. DS is 8 so likes impressive buildings and ruins but without having to use too much imagination.
