Before leaving I was quite afraid about the group and the effective chance to share this kind of experience with several people in a pre-arranged way being able to preserve its meaning. At the end of these 5 day I have to state that I really enjoy the experience. Ever and the other guys took great care of us (a great thank goes to the chef who always prepared great lunch/dinner).
I especially appreciate the small size of our group compared to other one, something which greatly help us in feeling the group as a family.
I would suggest this trek to other people.
