We had a great time at Carsten's place!!
Location is perfect if you want to kitesurf as you are only a few hundred meters from the best spot on the island. You can wake up and check the wind from one of the terrace, then start riding five minutes later :)
Communication with Carsten was also very easy, the way it should be. He even planned a transfer from the port at our arrival, which was very much appreciated after the long journey from France!
