We did a 23 days hike with Trekking Team Group in October 2018.
We were 100% satisfied with the overall experience of the trek. Everything was neatly organized. Communication beforehand was very quick efficient and in a timely manner. Upon arrival in Kathmandu we were carefully taken care of every single day. First by the agency (sightseeing/ evening dinner in Kathmandu) and later by our fantastic, very knowledgeable and experienced guide and porter. We booked a group trek but since no other people signed up for the same itinerary the trek was carried out as private trek without additional cost.
I am glad to have chosen TTG as operator and would recommend undoubtedly to everyone that plans to go trekking in Nepal.
