I stayed two times in Sankara. Very nice hotel. Personnel is friendly and always willing to assist you. Room are well designed even is the surface is a little bit under what should be for this category of hotel.
Breakfast buffet is awesome with very good products.
Only two points of complain:
1) When I was there AC in the gym room was not working and it was more a sauna than a gym.
2) Internet problem due to strange security certificates.
