Hotel Muli lived up to every expectation. Both the room and the bathroom were quite big, and everything was clean. Check-in worked smoothly. However, the owner really showed his excellence when our flight got cancelled due to bad weather, and we had to stay an extra night.
He approached us before we even knew that the airport would close and told us we'd probably would not be able to travel the next day. Then he said it was fine for us to stay for an extra day and night, *without having to pay any extra*. This is better service than anyone could expect, and the owner really showed himself as a gentleman in the right sense of the word. I will certainly stay here again next time I'm in Reykjavik.
