I stopped at Cabanas el Alquimista with 3 friends for two nights last December during our road trip trough Mexico. After a late arrival at night, the surprise was in the next morning when the sun and Pacific ocean woke us up in this great decor.
This is probably the best hotel I ever stayed in even if I didn't use much of the services offered. The athmosphere is very peaceful and you barely see other guests.
One personal negative note is to noticed: this place is too good to stay with friends, this is the perfect place however for a lover gateaway! ;)
