Good behaviour and professional but charges a bit more.
We took a 3 days / 2 nights rafting tour with Swissa. I did some rafting tours before and so far this one was the best. The guides were surprisingly well prepared and really professional (after seeing other things in Nepal, I wasn't expecting this level). The meals were great, diverse and more than enough for the group. They even prepared some fruits and popcorn! There were 3 safety-guides always around with one person kayaks in case rescue was needed but fortunately wasn't. I would definitely go again with them.
