Christian’s place is better than what is shown in the photos. Spacious and clean, equipped with all facilities of solid quality, the apartment is more than enough for me travelling alone. At the same time, even though it is not exactly located in the city centre, the apartment is well-connected with all sorts of public transport, tram 52and 60, and bus 12a. I stayed here for 5 days and found it easy to travel around the city.
When I checked in around 5 pm, the apartment was left exactly the way after the previous guest left. I sent Christian a message about the situation, and he responded very quickly. It turned out that the back-up cleaning lady had problems opening the door on that day, and therefore the apartment remained uncleaned. He soon contacted the cleaning lady and she came to the apartment within 20 minutes of wait.
To be honest, it feels awful to sit in a mess waiting for the cleaning lady to come (as I need to open the door for her). But Christian responded very fast, and suggested compensation for the troubles I went through. I really appreciate his reliability. All in all, I would recommend this place to anyone visiting Vienna.
