What to say except that we had a wonderful stay in Mark's apartment? The flat is nice, clean, quiet (away from street noise), the building is well maintained, but what is really great is the view on the mountains, from the kitchen where we had some dinners, and from the spectacular roof terrace. Having breakfast there (having direct access to the roof terrace is practical :) ) by looking at the Tramuntana mountains was ideal.
Communication with Mark and Marta was easy, all questions were answered quickly, directions given to the apartment are clear, and we had a smooth check-in.
Fornalutx is a good place if you want to hike throughout the island, and is a nice little village. To conclude: we definitely recommend this place!
