I own vacation rentals including one in Costa Rica, so I consider myself a pretty critical guest who notices details. Michael and Ed were awesome hosts, and their Ser La Luz retreat is really sweet! I stayed 2 nights while I recovered from dental surgery, and very much enjoyed the spacious & clean room, beautiful views of the volcano & valley, and their service. They arranged a driver to bring me from surgery, made smoothies for me, provided some aromatherapy, and otherwise did everything I could ask and more to make my stay great. I would highly recommend it to anyone seeking a quiet & health-conscious retreat in the Central Valley, and to workshop facilitators since their private indoor & outdoor spaces for group work are gorgeous. The only potential concern would be their 2 dogs and 2 cats for anyone allergic, but if you aren’t allergic, even the roosters seemed friendly. From what I could see, they are also continuously improving the facilities, so future guests will only have it better. I would stay there again, and highly recommend it.
