We used Upendra (Himalayan Leisure, Inc.) as our guide to do the Everest Base Camp trek. He took care of everything - flights (including some great queue jumping!), Sherpa/porter (brilliant guy!), tea houses (the best ones available), food (advice mainly - don't eat meat after day 4!), and worked with us to make sure that the trek was done at our pace, that we did get acclimatised to the altitude, and that we enjoyed the whole experience. His English is excellent, and he seems to know everyone on the route! We did this trek as part of a year travelling round the world, and the Everest Base Camp Trek was the absolute highlight of the whole year! We would highly recommend the services of Himalayan Leisure, and (if we ever get a chance to go back to Nepal - and I hope that we do!), we will be using them again to go trekking. ***** - 5 stars!
