There are two hotels called Miriam, I went to Miriam 2. It was the best value for money (payed about 15$ per night) It´s nice, clean and has view to the sea.
Go to eat at a restaurant called sunset, next to cabinas tortuguero, good price and cleaner than other so called restaurants. The arroz con pollo was great. Buda cafe has great pizza but overpriced more
