Karl is such a great guy! We enjoyed our stay there, we literally felt like home! I do recommend you to stay at him, you will be restless!!! The only bad part is that the location is in Son Ferriol, which is like 20-30 mins (bus) far from the Palma centre, but if you have a car, a scooter or a bike, you should not worry about that (even though with bus is all fine).
