I first "discovered" The Yak through a friend whom I visited there last year while she was travelling in Mexico. I instantly liked the relaxed, warm, hacienda feel of the place itself, so I sought out contact with the management. I kept in touch via email and returned this year as a guest. It sits right in the heart of town, no more than 6 minutes walk to either the beach, the bus station [direct to airport], the famous Avenida 12e for night clubbing, Avenida 5a for cafés, bars, shopping and the main grocery stores for food.
The big custom made bunks offer a comfortable nights sleep in the clean, spacious dorm rooms and the fully equipped private apartments/rooms make it very easy to feel at home away from home.
The atmosphere is super welcoming. The staff is very friendly and helpful in anything you want to know about the surrounding area. They organise weekly dinners and movie nights plus other activities and events that makes it fun and easy to meet other people in the already laid back, youthful, international crowd. Overall, it's a great place to stay and hard to leave.
From the delicious welcome cocktails to all the vacation conveniences, as far as hostels go, this spot is definitely the place to be when visiting Playa Del Carmen. Thanks a mill Yak, for a fantastic stay, I'll surely be back!
PS--Hayley (Australia) loved the hammocks in the courtyard!
