My guide, Rishi, was very kind and very professional, ensuring that the logistics of the trek were intact. I was a bit scared of the Tumlingtar flight but luckily this too went without any problem. On the mountains, my guide regularly checked up for symptoms of altitude sickness like oxygen, pulse etc. and we took appropriate acclimatisation days - because of this I had wonderful trekking experience with them. Porter was also very friendly and smiling.
