Thought the Olsen was quite a nice hotel. The room was beautifully finished and very modern in design. I was staying in a Studio, so there was a small galley kitchen that was well equipped.
The bathroom was a little small, with opaque glass walls separating it from the rest of the room. Nice and stylish looking, but not so good when the person you are with gets up early and turns on the lights! But that was a very minor annoyance.
Complementary tea from T2 was a nice touch, as was the better than average selection of stuff in the mini-bar, including multi-vitamins! The bed was really comfy, with super-soft pillows.
The restaurant downstairs was quite good, though a little expensive, and had very nice breakfast options.
