We were 7 colleagues coming for a congress in Vienna University. We had a wonderful stay at Veronika's and Johannes' place. The apartment location is central, very convenient for visiting and close by the university, and many shops around. Rooms are large, lots of light, bedding is very comfortable and very clean, and we had all amenities we needed in the kitchen and bathrooms. We would definitely come back if we have another opportunity. Johannes responded quickly coordinating our stay, he's been very helpful and nice with us. We totally recommend his place.
