Do not book this place. As you can see from other reviews as well, the check in process is impossible. No contact before we arrived, and no one at reception. There is a sign with a number at the reception but no phone to call from. We had to use our overseas phone, incurring roaming charges, but the manager will not pick up.
In the end, a builder had to call the manager on a private line and were provided with a room that did not have a kitchenette as we had booked. We complained to the worker who said it was not an issue and we had to call the manager. We tried again and she did not pick up. At this point, another couple were having the same issue. As we were both complaining to the worker, he locked himself away and stopped talking to us so we had nowhere to stay.
We had to call the police to try to get the issue sorted but they could not do anything. In the end, we were all refused a room, and had to travel 2 hours to Reykjavik to find another apartment.
Do not book - you will have no communication with anyone at all (not even on the phone or online), and the rooms you get will not have a kitchen or even basic utilities (kettle, microwave etc).
