As I arrived from New Zealand, based on my friend's recommendation I took 2-3 tours from Tamas, who has an amazing rich knowledge about the hungarian and Budapest places which are really rich in  experiences and excitments. He is very correct and reliable. Kept all his promises, showed me extra sights and was not costive with his time! I can only recommend him, he is an excellent guide and a very funny man in one person! :))
