We booked in the cabins/villas and our room overlooked the Arenal volcano! The room was MASSIVE, very clean, modern bathroom, and the bed was comfortable. If you are going to either Arenal and/or La Fortuna, stay HERE. There are regular rooms in the hotel building, but the extra bit for the cabin was the best.
The free breakfast was delicious, plentiful, and cooked to order. The WiFi worked well. Staff was very friendly and helpful, and spoke enough English to do the job.
Shout out to Restaurant 1 block away - Raul Castano - fabulous dinner also facing the volcano.
