To answer your questions:
1) We actually wanted to experience a new culture and also have some kind of adventure. We're already doing things in Spain, so we just wanted to try out something new and see how it works :-)
2) This was only a 2 month experiment, but our whole company is set up for remote work. So some of us continuously travel and work from different places. Myself I've been living in a camper van for a year now (blog post pending ;-)), but this was the first experiment where we actually rented two houses offshore and moved a bunch of people there.
Since then we also had another experiment. We spent some time in the Austrian Alps for skiing. We'll write about it soon.
And the next thing we want to do is actually in Spain (in the mountains) and then we're planning to go to Mauritius for a month or so.
