We found Villa Valhalla through Andrew, a rental agent at Sol Maya Rentals. It was our first time to Akumal and no one had a clue what to expect! It was absolutely PERFECT for our group. Complete Paradise. Highly recommended. The house was plenty big for our group (we rented 3 bedrooms at Balam Ek next door too!). In Villa Valhalla, there are 6 king bedrooms of equal size and each bedroom has it's own bathroom. There is a half bath as well in the main living area. The living space and bedrooms are bigger than the pictures let on, especially the kitchen area.
There are kayaks that you can use to kayak right off from the house and a few of us brought our own snorkels to use as well. You can also rent snorkel gear at the Akumal Dive shop - A short walk away. We snorkeled from the Akumal beach and saw giant turtles! The house is also a VERY short walk to La Buena Vita to have beers on the beach and enjoy some fish tacos.
The house was clean. Pool was wonderful. Staff was courteous. No complaints. Cannot wait to return.
We also used Paradise Transportation - Another recommendation from Andrew - To transport our large group (4 trips to/from the airport...It's a 60+minute drive). They were SO accommodating and we arranged everything prior to our arrival to make traveling with the large group so easy. Car not necessary if you only plan on hanging around Akumal. Thanks to Andrew L @ Sol Maya Rentals and everyone at Villa Valhalla!
