We have stayed here twice and have booked again to go this weekend. It's perfect for us. Cheap, simple comfortable rooms, nice staff and the bonus of the rooftop pool! The weather in Cópan is hot so it's great to be able to cool off after a day of walking or visiting the ruins and the view from the roof is pretty good. It's located one block away from the Parque Central so very handy for all the lovely cafes and restaurants in town and it's on the road that heads out towards the ruins.
Some reviewers have complained that the basement rooms are dark. However they are also nice and cool so we recommend the basement for a good night's sleep! There's plenty sun outside all day.
