The apartment is within walking distance to the Schönbrunn Palace, metro station, there are plenty stores nearby, bars and restaurants. The bed was very comfortable. The apartment is spacious and bright located in a very nice and peaceful neighborhood.
Max and his mother are very prompt and helpful. The communication was done very easily via Airbnb messages.
The pocket wifi that Max provided was very helpful.
A P+R garage is close by and it costs only 3.4 euros / day (Park + Ride garage Hütteldorf).
We gave a 3* for cleaning because there were stains on the kitchen cabinets and window curtain. Window frames were a bit dirty. The toilet and bathroom fan did not work as expected. Nothing too serious nor a deal breaker!
All in all the staying at Max's place was good and we would definitely book his place again when we return to Vienna!
