Harald and Karo's place was a beautiful and cosy apartment. Everything was sparkling clean and equiped with all the amenities mentioned in the description (which was exactly what we needed during our stay). Also, the bed was very comfortable so we could enjoy a good sleep after an extremely active day.
Last but not least, we were also given recommendations on cafés, restaurants and places to visit.
All in all, I recommend Harald and Karo's place for a beautiful experience in Vienna.
