Pros
I don't see any apart from the fact you'll meet cool people in a remote and nice place. Good holiday paced by daily 9am meeting that serves no purpose , and your typical camp tasks (cleaning, garbage etc etc.)
Cons
There is way too much to tell. But this place is nothing but a serious research base. This is a family business living off people's money / Erasmus grants. They have no support with the scientific community in fact it's hard to work if you require support from other organizations Most of the effort is put into digital communications, which shimmer an appealing opportunity we all fell for. I am afraid we are very close to what I would call a scam, and the problem is they have already started carving themselves a bad reputation amongst academics. In fact the only place where you will find feedbacks is here on Glassdoor and that is already a bad sign. Try to find any partnership with other organizations, or even some of their publications , read them, try to get in touch with people that have been working there... You can even search for the "Archipelagos institute of meme conservation" on Facebook. Places like this needs to be shut down. Look somewhere else.
