I booked heli service for morning but had to wait for a couple of hours due to bad weather and bad visibility. Naba personally handled this situation by updating me about the heli service. He messaged me time and again updating about the weather to fly to Lukla and EBC. Luckily it opened before 12pm and I was on heli on before 12pm. The heli took me to Lukla, EBC and Kalapatthar and Syangboche hotel for breakfast, although it wasn't breakfast for me. When I was back to Kathmandu, met with Naba in Thamel and shared my experience with him. Highly recommended service for heli tour to Everest.
