I spent 4 weeks at Ananda Yoga Centre doing the Yoga Teacher Training. The accommodation is modest but very adequate. Located about 1 hour from Kathmandu City, situated far enough away to be away from traffic and pollution and able to enjoy the fresh air.
Lovely vegetarian food provided every day. The daily routine includes Yoga 2x's a day, daily yoga Nidra (deep relaxation) and Kiritan (singing) nightly.
I recommend this place for a restorative experience.
