I did island peak 3 days, due to logistics it ended up being just me which was great, Bimal was my guide and he had experience of multiple successful summits on Everest Lhotse Ama Dablam and of course island peak.
I didn’t succeed in the summit but Bimal helped me a lot by sticking to my pace, shining his light on my route, pointing out the best paths to take and giving some pre summit training.
Tej the owner of Nepal Alternative Treks was helpful in explaining logistics and answering questions.
I would recommend Nepal Alternative Treks especially for people wanting to either trek solo or guided, and for both beginners and experienced mountaineers.
