EXIT-Madrid has one of the best staff teams we've encountered in any escape room. From the moment we entered the building we felt very welcome, and there was no waiting around. After we put our bags into one of their lockers, we were led to a briefing room. This room is designed to seat a large number of people, presumably to cater for corporate groups.
On the day we went, it was just the two of us. They played a video with the standard instructions with rules and tips for solving the puzzles. Then Alex, the owner, came in and chatted with us about our previous experience (we mentioned we'd done quite a few escape rooms) as well as what to expect. It was a casual chat between fellow puzzle-lovers, and it's obvious how passionate Alex is about puzzles and narrative.
As expected after such a great start, the room didn't fail to disappoint. This is a place we would return to again and again!
