Expensive, hot and I got a room that should never have been avaliable. Pick any other hotel in the town of Örebro and you will get at least the same if not better experience for less money.
The room had a constant background noise from some kind of generator, most likely connected with the relax-spa on top. It was always on which made it very difficult to sleep. When I complained about it, all other rooms were booked (true). But the staff seemed not the slightest surprised about it, they no doubt had heard that complaint before. So this hotel has issues when it comes to leadership, they focus on making money thanks to their location just across from the Conventum. Add the name "Grand" and it will always get people to stay there.
The hotel itself has the reputation of being the hottest hotel in town. it has always had that issue for the last decade, but once again, seems not to be prioritized. I wonder how much money the hotel could save by actually trying to lower the heating cost... My guess, quite a lot...
So find another hotel to spend your money on. This one just isn't worth it at all.
