Carl's house is really cozy and lovely. I couldn't meet Carl becuase at that time he was travelling but he cared by app and his girlfriend Martina really cared me. This apartment is a bit far from city center (25-60 minutes, depends on islands) but for me it was still nice as I like calm and more local area. And this apt is super closed to the nature, there were two recommendations from Martina, park and lake and I really enjoyed having time there. You could see best sunset in both places.
