Our guide RD Tamang was fantastic, he is well experienced in the Everest region and very tentative to our needs. When we felt sick near the basecamp, he advised an alternate route to go down first and then use a different (very quite and nice) trail to reach Gokyo, which was critical for us to finish the trek. The Kathmandu tour was also nice, and we had a very nice welcome/farewell dinner. Last but not least, I find the price very reasonable for a 20 day itinerary with all meals, airplane ticket (from Kathmandu to Lukla), and accommodation included. Would highly recommend.
