I stayed at the Blue Morpho House for one month, and I can say it is my favourite place in Costa Rica. Melissa, Made and Raquel, the three sisters who manage the hotel, are some of the nicest people I have ever met, and I now consider them my friends for life. They are always smiling, helpful and kind, and personally showed me all around the local area (including snorkeling at Playa Biesanz). They also taught me mucho español. They even very sweetly invited me to eat Christmas dinner with them, which was amazing.
The hotel is extremely clean and quiet, with all the amenities you could need, you may even see sloths and monkeys in the garden. The location is perfect, it is just off of the main road between the national park and Quepos (both s very tasty and healthy. Highly recommended. They also provide a good, cheap laundry service.
I feel genuinely sad to be leaving, but I will be returning again and again in the future, and keeping in touch with my new Costa Rican familia.
