We had a very enjoyable week here in Sept 07 as part of a
'Headwater' walking holiday. Don't expect a clinical hotel, As the name suggests, this is a beautifully restored and extended farm house
in mountainous terrain, run by an English couple with a friendly cat and dog. The food and service were amongst the best we have experienced anywhere.
The Finca has a large comfortable lounge/dinning room with roaring log fires in winter. During our stay, breakfast and most meals were taken out on the terrace (overlooking the valley below). There is a library and - refreshingly in this day and age - an honesty bar. The room, pool and gardens was kept clean and tidy.
The hotel run painting, writing and pottery courses (in a purpose-built studio) and as far as I know are open all year round. We have no knowledge of how good (or bad) these courses are, but the owners seem very conscientious and I couldn't imagine them putting on anything that wasn't 'up to scratch'.
I wouldn't recommend Finca el Cerrillo to bored teenagers or anyone who has difficulty in walking. The pool is quite deep and and there is no childrens' pool, so (as always) you would have to keep an eye on young children in that area. If you go as an independent traveller
you will need a car.
I would recommend Finca el Cerrillo for anyone interested in the activities mentioned above and of course walking and bird watching (how I wish I could have taken my mountain bike). Also honeymooners and those who prefer to chill out by the pool far away from the madding crowd.
I noticed some riding stables on the mountain road between the hotel and airport so there might be some riding possibilities there, given a bit of research.
