The room was spacious and well laid out however, very dark. There was no main overhead light to turn on that illuminated the whole room. We had to go round and turn individual lamps on. Some of these were unplugged on arrival, so it took a while before we were even able to see the room properly. The safe was impractically small and impractically high up, so we weren't able to use it to secure a MacBook at all, despite having rang ahead to check the size - so unfortunately no use.
The room was clean.
The bathroom very inadequate - a tiny shower with a hanging plastic curtain, but a space so small that it became your best friend. Toiletries were provided, but very basic.
The bed was comfortable but we were cold in the room on the first night, and asked for additional duvets which were provided. It was a king-size bed but you were given two individual duvets. Maybe that's the Icelandic way?
Breakfast was good with a decent selection of choices. There is a very basic gym and spa.
Overall a nice clean hotel in a very central location, but lacking in some basic facilities.
