If you are sick of sitting in a bus hearing a recorded voice all the time and just passing the main attractions a private guide in Budapest could be interesting for you. These guides show you places which no large group organized tour will show you and they always have an interesting story to tell.
Private guides usually have a better knowledge about Budapest than large, organized tours and can show you hidden places and tell good historical stories about these places. Additionally you can ask the tour guide to show you places you want if you have any favourites because the private guides are much more flexible. Of course a private guide is a bit more expensive but if you are a group of 3 or 4 persons it is a reasonable price for the information you get. Check out the private tour offers in Budapest.
