My mother and I spent four nights in John's apartment. The flat is central (Mariahilfer Straße and Westbahnhof right around the corner/30 minutes walk to the city centre), well connected to public transport and located in a quiet street in a nice building. The kitchen and the bathroom were clean, but unfortunately not very well equipped. In addition, the shower cubicle was broken. We also had a power cut on the first morning and consequently no hot water, but John took care of the matter very quickly. There were also a few problems with the check-in, but this was solved by the problem-free communication. John made up for most of these difficulties with his helpful and courteous manner. Thanks again for your comprehensive help!
