Don't hesitiate. Just book it. This place is amazing. The view is jaw dropping, as is all the scenery in and around Llançà. If you've never been to this part of the world, you need to.
Imma was a superb host. She met us late into our first night (train delay) and greeted us with a smile, a thorough tour of the place, some local tips, and some local wine and cookies! She was extremely responsive to messages leading up to our visit, and made us feel very comfortable coming to an area that was unfamiliar to us.
Highly recommended! Five stars!
