The accommodation was nice, as were the Dutch owners. The problems for me were that I was a solo traveller and also the only guest. So it was a bit lonely. Also, Tongkaina is very quiet. Lunch was not included and the only options in the village seemed to be a couple of dirt-floored warungs. The third thing was that, if you are a snorkeller, it makes more sense to stay on Bunaken, cos the Grand Luley boats take you to Bunaken anyway.
