Depends on what part of Budapest. One of the reasons people like Zugló (14th district) is the many trees. And farther out it's even better, of course.

But a lot of the trees in Hungary just don't grow that big, maybe the most marked difference when I first saw it after growing up in Indiana. When we lived in the 16th district of Budapest, there was one neighborhood I used to walk the dog in that had these massive old American sycamores. Those things were beautiful.
