We had a lovely stay at Astrid's place. We had the check in details before reaching Vienna and were also able to check in earlier which made things very convenient! The apartment was very clean with all amenities as advertised. The location was also very convenient with a bus stop and tram stop close by and Rathaus within walking distance. I would recommend downloading the Qando application while in Vienna for understanding public transport routes and timings since Google maps doesn't work here for this.
Lastly, Astrid was a great host who promptly replied to all my queries even though she was on vacation - thanks for that, Astrid!
