Great shots. Budapest is definitely one of my favorite cities in Europe. I was a telling a friend that I think they must have had the blue hour in mind when they were building the city, there are just so many great locations to get great pics in the evening.
I was there four nights in June and it just was't enough time to see everything and get all the pics I wanted. I think I need to go back and spend at least a month there some time.
Yep the blue Danube isn't blue in the daytime :)
