Jakob is a great host, although we didn't met him because he was away for work: communication was easy and very attentive, he organised that a friend of him welcomed us at our arrival. He also kept in touch with us for further questions. The apartment is amazing, very well equipped with everything you need. The only drop of bitterness was that we couldn't use the balconies (there are three of them!) for breakfast because of the weather. I highly recommend the apartment!
