Nautilus is a wonderful little hotel situated 3-5 minutes (by foot) from the beach. The location is excellent for those who want a quiet place to stay in the sleepy surf town of Santa Teresa.
The hotel is very clean and each bungalow has it's own kitchen area, living room and separate bedroom. Note that AC is only available in the kitchen/living area, and that a ceiling fan is in the bedroom. Breakfast is included in the cost of your stay and there are many delicious and nutritious choices, including an amazing full breakfast with small smoothie and wonderful gluten-free pancakes. Karla the cook, is lovely and everything is prepared fresh for each order.
A couple peculiarities include - no food being served in the hotel restaurant on Saturdays and no housekeeping on Sundays. This isn't a big deal, since there are many places to eat within a short walking distance, including my favorite local-run cafe, Soda Tiquicia. There are many food options in Santa Teresa that offer burgers/pasta/etc, but Soda Tiquicia offers authentic Costa Rican food at very reasonable prices. I would highly recommend the Casado con pollo or seafood soup. This little gem is located about 400 metres from Nautilus - turn right once you hit the main road after you exit the hotel.
The owners of Nautilus also live on the property and are lovely people who seem to genuinely care about the guests. I can't say enough about this place and hope to return in the future. It really is a paradise.
