I am going to split this review in 2 as there were issues out of the control of the hotel.
1: Staff were fantastic, despite the issues in item 2, they remained friendly and helpful throughout, the room service waiter was without a doubt the nicest chap EVER. The food was very good, and the room was comfortable and (unlike a lot of hotels in winter), I was able to get the temperature cool enough to be comfortable. Check out was a breeze and the bus TO the airport spot on.
2: This hotel is evidently used by AF/KLM to accommodate stranded passengers, and on the day, I was checking in, a LOT of flights had been delayed, yet there was only a 20-person minibus and at least 80 passengers needing transportation, this ended up with me paying €33 for a 10-minute taxi ride. On arrival at the hotel, the queue was huge, and, although dealt with effectively by the hotel staff, still resulted in a good 30–40-minute wait.
I know that the use of the hotel by the airlines is a little out of the control of the staff, but the morning shuttle was a full-sized coach, which should have been used in the evening, when they knew there was in instant high-volume demand. Would I stay here again? Well, I do like the Steigenberger brand, and the one in Hamburg is one of my favourite hotels, but the sheer inconvenience caused when used by the influx of stranded passengers will certainly make me think twice.
