I stumbled across a site today advertising a couple of water mills for rent. Below is an extract from the page.

In the South of Spain, in a lost valley between Ronda's mountains and Grazalema, next to Gibraltar, in a beautiful landscape   and crossing a  hanging    bridge  very long, we offer you two old completely restored Mills of Water, one of them (the Flower  that gives the name to the whole group) leaning in  the remains of a Roman bridge, both with the water happening  under theirs and front the rapids of a mountain river, sportsman paradise, fishermen, environmentalist and also for golf 's lovers.

(…)To enter it is indispensable to know the access key that you need to open the grate in an automatic way. This road allows to arrive in car until the same door of the mills, but IF you doesn't HAVE VERTIGO  we recommend other, using a clearing in the forest adapted for parkings that exist in the other bank and  crossing a  HANGING BRIDGE. It is not necessary to arrive to the town or the station. In the crossing, continue for Cortes of the Frontier, and less than a kilometer, passing a camping previously, and looking to the river,  you will see our entrance very signalled with a poster in a post and two mill wheels, and after the door -that only opens if you knows the key - and you will see the parkings.

We NOTICE YOU THAT IF YOU HAS VERTIGO TO THE HEIGHTS, you won't BE ABLE TO to PASS THE BRIDGE,   it is VERY HIGH AND VERY LONG (about 60 metres)  AND IT MOVES VERY MUNCH, it is similar to the of Indiana Jones, but in sure, -always that you doesn't make foolishness -.

KITCHEN’S SERVICE

(…)The property only offers lodging, but the ladies who do the cleaning to us are housewives of the place and like such magnificent cooks. Directly contact with them -tfno 952 …, and the international prefix,  Mrs. Paca, only in spanish- and say that kitching for all the group a big “paella” or some typical spanish meat to them and that soon leaves all clean one and gathered.
