We had a great stay at Eco Arenal. We only stayed one night, but I wish we could stay longer and take advantage of the beautiful grounds and the pool. We arrived earlier than the check-in time and after checking that our rooms are ready the manager on duty let us check -in. The rooms were roomy and very clean and neat. All the villas looked great( we booked 3 units) and well maintained. The grounds are so beautiful, with many different kinds of flowers, bushes and trees it feels like you in the botanical garden. The villas are also located outside the busy touristic area so it is super quiet and relaxing. The breakfast, which is included, was simple, but very delicious. We had rice and beans( it is served everywhere and with every meal in Costa Rica), scrambled eggs, ham, potatoes, fresh papaya, pineapple, bananas, bread basket, coffee, tea, orange juice. It is served starting at 7AM, so we had plenty of time to enjoy before going out to our activities. We were 8 adults in our group and everyone agree that we will stay there again if we're lucky to go back to Costa Rica.
