Spent four nights at Katharina's apartment. Never met her in person but the communication was top-notch. Her grandma, who lives nextdoor, helped us checking in and out. She's probably the single sweetest person in the world and made our stay even more enjoyable. The apartment itself is a little small for three people (sleeping in separate beds) but to be fair, Katharina arranged the third bed for us which was super nice. Aside form that the place is clean, well-equipped and really serves its purpose. The garden is also great and the price is more than fair. I can only recommend!
