It's strange that the number 1 attraction in Budapest really has nothing to do with Budapest, but just happens to be in the city. But it is absolutely worth going.
There were three of us to went, and we found our way out fine (with a little help). It would've been next to impossible I think to do a couple of puzzles with only two of us.
It took a few minutes to get into the swing of things, but once we did it was a thoroughly enjoyable hour. I obviously won't go into any details about the puzzles themselves, but on the whole they are well devised and brilliantly executed.
If you're in Budapest, find TRAP and enjoy it.
