The apartment was very nice, like the pictures show. Arndt and his brother clearly make an effort to welcome their guests and it shows. Only issue we had was we arrived as a family of five with three small children and there was no flexibility to check-in or even leave our stuff or car at the apartment until 1500/3pm, which was exhausting since we arrived early that morning from a transcontinental flight and had no place to rest, leave our stuff or car.
Last comment would be, we were there in the summer and it unseasonably hot; there are fans but no air conditioning, so if that's something you need definitely read the fine print as much of this part of Europe has no A/C.
We would recommend this place though for its location and decor and the host was very friendly.
