I was in Stavanger to go to The September When concert at the DNB Arena. The Clarion Hotel Energy is literally just next door, so I didn't have to think about how I was going to get back to my accommodation after the gig.
Added bonus: the hotel is halfway between the airport and the centre of Stavanger. The airport bus (FB40) + regular buses and night buses stop just outside. Alternatively, it is an easy walk (past a lovely lake) or cycle to the city centre. Taxis also seem readily available at the hotel.
The hotel is also in the vicinity of other big sports complexes, a conference centre, and Sverd i fjell (swords monument), so it seems to be very popular for multiple different groups of guests and has the capacity to accommodate everyone.
I chose one of the smallest rooms at the hotel, but it looked new and the bed was super comfortable. I had the best night's sleep! And a nice, powerful shower!
My only negative: I really wanted to get room service after the concert**, but there was no menu or QR code in my room to do so. I ended up walking to the 24-hour petrol station 5 minutes away to get some late night food.
**It was after midnight and the hotel's restaurant/bar had closed for the day.
