Truly beautiful city, and easy to walk around the city centre.
Quite expensive when you are there, but on the positive side, unlike lots of other beautiful European cities, which people go to for a city weekend break, you won't find loads of British stag and hen parties weeing in the fountains!
I once went out with someone from Salzburg, and they are very nice people, and like us Brits.
If you decide to go I'm sure you'll love it.
Great place to buy just one hot chocolate, and sit and people watch at a street cafe.
