Great location but the listing is not accurate. I had a tiny room with a view over concrete. When I asked to move they said because I was a solo traveller they couldn't give the same size room as the description even though the price I paid was the same. That said breakfast was good.
The clientele were mainly 20 year old German and Dutch boys and girls - respectful and fun but not a relaxing group to sit by the pool with.
Location was great and Arenal is a typical beachside resort
