There are many guides to choose from. We chose Jana and we were delighted. Three hours of information, history, top tips, sight seeing etc – all part of the Grand City Tour starting at 10.45 in the Old Town Square. We learned so much about this beautiful and fascinating city and were signposted to good places to eat and drink ‘off the beaten track’. We took up almost all of them and were were pleased to have done so. Marvellous. Payment is via tips.
