Accommodation:

Airbnb in Coco Beach (8/10): Coco Beach is a perfect location for getting around to all of the best spots in Guanacaste! There are plenty of delicious restaurants and bars to choose from!

Must See Places: 

Being 100% transparent, if visiting Costa Rica, I would only spend 2 full days in the capital, San Jose. Pay a visit to Alajuela, Hacienda Alsacia Starbucks Coffee Farm (the best Starbucks I have ever visited), and Poás Volcano before departing the capital. If you have an extra day, I highly recommend booking a trip to Tortuga Island!

 Now if you're ready for a fun road trip, here's the list: Monte Verde, a mountain top jungle hidden in the clouds and full of adventure; Arenal Volcano in La Fortuna; La Leona Waterfall, be prepared to wade through a river into a cave waterfall (buy tickets in advance); and finally head to the beautiful coast of Guanacaste! Ocotal Beach, Playa Conchal and Playa Grande are my favorite beaches in the world! They offer the most beautiful sunsets I have ever seen!​

I MUST ADVISE, Public transportation there was very unreliable for us. We were taken to the wrong place multiple times. Uber is very expensive and the roads are very bad making it hard for some Ubers to get to their destination. I recommend a rental car, but only if you feel comfortable driving in dangerous conditions. The roads are practically invisible especially in the mountains.
