I've spent 2 weeks at Vikings in a superior room.
Room is big and ok. The big issue is the water pressure, it's almost impossible to take a shower.
Staff are a little bit lazy and the owner is cold, he said only once Hello even if he showed me everyday.
The laundry service is a scam, it's written on the rules 50p per kilo, that's all. But if you give about 1.5 kilo they'll charge you 150p. I argue about it, and their answer was the laundry shop charge a minimum of 3 kilo.
I didn't try the swimming pool nor the food as I find it expensive.
Don't stay there!
