We enjoyed our night there, Sekiu was a very cute little town and the marina was nice too.
For what we paid, we wished the kitchen would have been slightly more equipped (bigger bowls, larger pots, drying rack for the dishes).
The room had a light musty smell, maybe airing it out from time to time would help, but maybe that is just part of being located 50 foot from the sea.
The staff was very nice and checkin was easy.
Overall, would have no problem recommending this motel for a short stay.
