Last week my class went to Budapest. It's really a nice city with a lovely atmosphere, especially at night.
The place 2 be? - definitely the stairs in front of the St. Stephan's Basilica.
If you want to have a cheap but fairly good breakfast, I recommend you the "Bali Café".
So the city is very cool but the sightseeing tour wasn't. We hurried from sight to sight from 8 o'clock in the morning to 11 o'clock at night and hadn't much free time. So we were very tired and on our nerve ends.
