If you go to Granada, you must go Hammam.
Its beautiful interiors are a reproduction of the original arabic baths of La Alhambra.
It has three pools: cold, medium and hot water, so you can take relaxing contrast baths in them. It has a sauna too. For a really good price, you can spend 2 hours in the baths with a really good aromatic massage.
The place smells so nice and relaxing and you have little comfort spots so sit down and have some tea.
Don't miss this experience!
