Budapest seems different from other cities I've looked at so far. The sights to see is the city itself, than any particular attraction (e.g. ancient ruins or palaces/museums). And by the city itself, I mean the bathhouses, ruin bars, heros square, etc. Things that one experiences themselves rather than getting a tour guide through. That being said, I've been trying to figure out the best way to see it all.
I will be in Budapest on the 12th/13th of August (unfortunately, cannot change these dates). There are unfortunately no concerts, shows, or festivals these 2 days. So I was curious, is it best to just rent a bike for the day, and ride around visiting the various buildings and attractions (e.g. one day one side of the river going to the Széchenyi Baths, Parliment, Great Market Hall, Great Synagogue, then the other riding through the other half to see Mathias church, Rudas Baths, Memento Park, etc.). Or would it be better to get those hop-on/off tour busses, or maybe a bike/segway tour that takes you through the city with a guide.
