I did the YTTC Ashtanga Vinyasa 200 hours last October 2018. I was the only student as it was still low season, but it was great to have private lessons from the best yoga professionals. All local teachers were excellent, specially Dharma as yoga teacher, both for morning asanas and adjustments. Ramesh Kumar is also excellent teacher for pranayama and therapeutic yoga. Shaila-ja is remarkable teacher for Anatomy lessons. Also, my gratitude to Somashaker (philosophy and meditation), Shantharam (shatkriyas and mudras), Sunny (chanting). It was a very special experience.
The center includes all facilities, very simple and clean most of the time. Do not expect any luxuries here. It is managed by Harish and his brother Ueno, loving people that treat me like I was family, I will always be grateful to them. Kumar, the cook, is excellent! Best cuisine in Mysore, all vegeterian!
The location is good, in Lakshipuram neighbourhood, close to the palace and bazaar market. It is 5 km away from Gokulam, the epicenter of yoga ashtanga in Mysore, so do not expect many foreigners here. Out of the western crowd, Just a few of foreign people here, which was perfect for me. They would join for morning asanas class (from 6-8 am, we were maximum 4 people in busy days).
I highly recommend this place, both for YTTC as well as for daily practise. You can rent a private or share room and join any yoga lessons you prefer: from ashtanga to hatha, back bending, pranayama, within many others! Also ayurvedic treatment and courses available.
