This is a very clean and nice property. The level of service and amenities does not match the price. We have stayed at places in Costa Rica that are nicer and better attention to detail but for much less money. You would think that breakfast should be included at the very minimum. Bring your own water to drink they charge $4.50 for a 20 ounce bottle. We would recommend the La Paz Waterfall Gardens as a day trip but find other lodging nearby if you are price conscious. Also, there are lots of steps no matter what part of the property you are going to. If you are not able to do up and down stairways very well then do not stay here. Good experience overall. Too pricey.
