We had a wonderful stay at Casa Sirena Azul. The home is very private and secluded. The grounds are gorgeous with a very relaxing area around the pool for birding. The pool is the perfect temperature and there was a young man who cleaned the pool a few times during our week stay. Listening to the abundance of birds flying in and out of the massive mango, palm and other lush indigenous trees, calling them with our Merlin Bird App, watching Capuchin crossing through the yard, hearing Howler Monkeys was heavenly. Waking up to the gorgeous waterfall just outside our bedroom window was so soothing. The check in process with Christina and Eric was flawless and they were very accommodating. The downstairs living area needs a bit of a pick me up, older uncomfortable seating. Somewhere to put your feet up for multiple people is definitely lacking. Somewhat deceiving from the pictures online. The lighting downstairs is awkward, too much LED lighting. The kitchen is well stocked and we made all our meals at home. We enjoyed the fresh fruits, vegetables, fish and chicken from the local markets. The upstairs shower does not have adequate pressure, so we showered on the second floor. The chairs around the pool need a small table to place drinks or appetizers on, one of the pool chairs needs repair. We felt extremely safe at Casa Sirena Azul and will return to Costa Rica soon!
