We've spent a wonderful time in Guillermo's house in Caimari. From there you can visit Sa Calobra, Soller an other wonderful places easily with a rented car. Buses will also bring you to most places but only one or two times a day.
But most of the time we spent in and around the house and enjoyed the warmth of the mallorcan Sun even if we first had the idea to go hiking every day :)
It is really a lovely place and you can have a perfect barbecue using the huge old stone fire place.
The place was perfect to relax for a week!
