We (4 of us) came across Good Vibe Adventure on a cab to Thamel from the airport in Kathmandu.
On recommendation and also because of tight schedule, we did an 8 days trek to and fro ABC. But I felt that 9 days would have been better and less rushed, especially to cater for contingency such as bad weather.
The guide and porter assigned to us were patient, professional and diligent in helping us out throughout the trip and ensuring that we were okay in the cold. One special aspect about it was the cultural meal that they brought us to on our last night back in Thamel, which was an interesting experience.
It was an enjoyable trip overall and I would look them up again should I go back to Nepal.
Thank you for your hospitality!
