Christoph was really helpful with our queries even before our arrival. His apartment was gorgeous with high ceiling, huge space with elegant decorations. It looks exactly like those in the pictures. We was greeted by beautiful flowers & a congrats note on our wedding by Christoph in the room. (I did communicate to him earlier that this is going to be our honeymoon trip) He was very friendly & speaks good English. He gave us the map & explained in detail on places to visit in Vienna. The cafe that was recommended by him for breakfast was fantastic. His apartment is very near to metro station (5min walk) & 10min to city centre (2station away). On our last day, our flight was at night hence we checked in our luggage from CAT City Check-In Terminal- 1 station away from the apartment and walked the whole day freely w/o luggage. We would highly recommend Christoph's place to stay at Vienna.
