Beautiful city, easy to walk with average fitness. Hop on hop of bus a must , book for 2 days much cheaper( only 5 euros more than 1 day). Don’t miss Margret Island , lovely to cycle around. River cruise day and night. So much to enjoy , Thermal bathes and New York Cafe.
It is a cruise without audio guide, but it is the best value for the money. I recomend to take this tour after you check and see all the building by foot and to pay attention on the cruise on the mail buildings such as Parlament, Buda castle, Fishermans bastiona, Gelert Hill and the Citadela. Also, is is very beautifull to cruise under the main Budapest bridges such as Chain bridge, Elizabet bridge and the Margits bridge.
At first we thought we wouldn't all fit on the boat because it was so full. We couldn't sit upstairs, but we could sit downstairs at the table, where the chairs were much better anyway. Also, we could rotate the chairs and you could open the windows downstairs so you could see everything great. It was an absolutely beautiful ride and the time (9pm) was perfect.
Great evening cruise the sights are fantastic, excellent value, the only thing to make it better would be commentary about what buildings we go past with a bit of there history
