The yoga at Yoga Dicha studios is excellent: there's a wide variety of classes to choose from - from demanding vinyasa to restorative yin and sound therapy - and every instructor I practiced with brought something new and interesting to the practice. I definitely recommend this studio!
Estancia Juneja is a cute restaurant in the center of Tulum which does very good vegetable enchiladas and juices. I didn't stay in the advertised hotel as it was fully booked, but the Airbnb provided instead was very nice and the hosts were excellent. I wouldn't normally order a massage for myself, but it was excellent too - I definitely needed it after all the yoga, cycling & swimming of the week!
