I've got a line on a very nice place that I've already rented for Feb. and will rent for Jan. as well if I can find a roommate or two. It's in the Nosara area of Costa Rica right on Playa Guiones.
Here's the details:
This private home is situated near the beach path of the Harmony Hotel has its property line ending right at the 200 meter mark. What that means in a nutshell, is that you're right at the beach. Not to mention that while this home has fantastic privacy due to all of the exotic tree varieties on the property, you're walking distance to almost everything in town. Bars, restaurants, the mini-super, video rental, internet cafes and shops.
Two story home. Three bedroom, three bathroom set up. Large upstairs balcony, living room area and kitchen in the downstairs. Concrete construction. Oversized lot w/ 1,599 square meters. Home is 1,950 square feet.
The house also has WI-FI so if you need to work (as I'll be doing) it can be done from the house.
PM me if you're interested.
