We stayed for a couple of months during difficult times. It was across lockdown but despite that the location was still excellent. It is a lovely walk into the city through pretty Neubau and the Museums Quartier or along the busy high street of Mariahilfer Straße. There are also excellent transport links with bus, tram and U-bahn all i the immediate vicinity. It's easy to get into the centre as well as venturing further out to Schloss Schönbrunn or Lainzer Tiergarten. There are plenty of interesting shops to walk around in Neubau and it has a nice feel to the area. Bars and restaurants aplenty - although none that were open due to lockdown for us - we will be back to try them!
Christiana is an excellent host and always responded promptly to any questions we had. We also took advantage of the offer of a regular cleaner which was really helpful and would well recommend. My husband worked from the office and we found that worked well. I would recommend Christiana's apartment as a great base to explore from, it is on a quiet street in a quiet courtyard of a Biedermeier house within a busy and interesting area.
