We (2-up, a third full of fuel) took a PA28-161 into/out of there last July, had no problems with rough ground but I agree it was a bit damp at the extreme east end. Landed to the west (up slope) and departed east in a 5kt southerly - I wouldn't want to try a westerly up hill departure, you might want to factor that into your planning.
Very pleasant stay on the island, the hotel was welcoming, good food. I'm keen to go back this year. The island belongs to the islanders now, I understand, so there's an element of supporting the community too.
