Donald's guest house was perfect - spacious, clean, well designed and well decorated. It is positioned close enough to the restaurants and the beach and yet very private and out of the main road.
Highly recommended !
Starr's place is perfectly situated in Playa Grande.
If you want a quite, secluded and affordable place, close to what can be called a perfect wave, with miles of pure sand beach in Costa Rica, then it is the place for you. I recommend to have/rent a car as the stores, restaurants are 10-20 minutes drive away. The place remains cool without AC ( which is also available ) even during hot days and all amenities you need are there.
