Hey everyone

Just a quick information you guys might help  me out with. I have some foreign friends planning for trip to Kathmandu, but they want to stay as paying guest so they will get chance to learn more about Nepali lifestyle and cultures. Just few bits of information they would like to know regarding how much they charge for each person. It might be B&B. They are planning to stay  for half  month. Any information would be so helpful, thanks  in advance.
