(To ensure English players - this is the famous The Lost Treasure of Alexander von Humboldt ranked #9 worldwide in Top Escape Rooms Project 2019 and #5 in 2018).
You know the escape room was good when after escaping it you cannot create in your head a 3D map of all the places you've been to while playing it. This room has exceptionally high production value. I am not 100% sure about it, but I have heard that some of the props used were actual props from the Indiana Jones movie. The architecture and scenography are very strong side of this room. All the lightning and the soundtrack are incredible as well. This is even more impressive once you hear that this room was built in a freaking 2015!!! This is madness.
Puzzles in this room were still good but not up to par with the very high production value set by looks and shape of interior and it generally seems to be agreed upon among people I asked. But don't get me wrong, they still guarantee a very enjoyable experience. At one place you may be tempted to "guess the last digit". I was a bit disgusted by the poor design of this element, especially seeing how easily it could have been patched this time, but please listen to me and this one time resist this urge to "guess the last digit" if you want to have the full experience, because you should really enjoy your time in this beautiful room and that is neither some competition nor the right time to "punish designers" for their bad decisions.
One more thing that deserves the mention is very good customer service. Immersion starts definitely before the game starts with a very good Game Master acting. To seal the great experience, we got definitely the best photo I have ever been taken in an escape room. On the bad side we got some unwanted hints :(.
By the way, make sure to book this room A LOT in advance, cause this is so popular basically all the spots for the closest two weeks are fully booked. And make sure to visit Brandon Darkmoor as well, because this is the award winning room too, many people prefer it even more than the Lost Treasure.
On a personal story note, how did I end up in this room? My friend asked me about some escape room recommendations in Berlin since he will be there in two weeks. I have never been to any of them at the time he asked me, but I have heard great online recommendations for this room, so I told him about it. ~Two days later he asked me whether I would like to join him. I got no reasons to be in Berlin at that time and I live in Warsaw, but as a crazy escape room enthusiast I quickly searched trains online and chose one that departs at 5:36 AM from Warsaw in order to go to "Go West" room (in The Room as well), then to this room and then to return the same day to Warsaw. Definitely worth it!!!
In my new rating scale that I decided to adapt (1-horrible, 2-ok, possibly flawed, 3-good, worth doing, 4-very good, 5-extraordinary) I grade this at:
Set design: 5
Something original: 4
Did I have fun?: 5
