For everyone visiting the Casa Verde with kids, keep in mind that Daisy (she has been a very reliable and knowledged nanny for both of our kids) can help you care for your kids, so that you might have some more free time. You can hire her for US$30 per day (8am to 5pm). She is also a great cook - try her ceviche and salads. Just let us know and we help you coordinate her visits.
I first came to Costa Rica in 1998. I fell in love with the country right away for so many reasons. I have been coming, living and unfortunately never staying off and on since.
