What a gem!
If you need to be centrally located in Vienna and would like a place with two large bedrooms (each bedroom has a bed for two) with adjacent walk-in closets and renovated, MODERN bathrooms, look no further.
The Opera, St. Stephen's church, the Kaerntnerstrasse, the Graben, the Hofburg, the Sacher, the Jewish Museum, the theaters - all main attractions were in walking distance.
To get to the airport go to Landstrasse Mitte and take the 15 min CAT that runs every 30 minutes (if you are flying Austrian airlines, you can check in your bags at the counter at Landstrasse Mitte ).
The hostess is charming, efficient and responds promptly and reliably.
The apartment was spic-span, had all the amenities an AirBnBer might need, is well-thought out and our favorite - very high ceilings - as it is on the 1st floor (1st floor in Austria is not ground floor - more like 2nd floor. The building has a small, modern lift/elevators to haul your luggage - and you, if tired - up to the 1st floor).
Even though the apartment is only a stone's throw from the heart of Vienna it is located in a quiet, short pedestrian street that connects two calm cul-de-sacs. So if you are the partying kind you can easily roll back from your night-club in the 1st district and collapse in bed. If you are the quiet type you will enjoy the peace of this location.
If you are renting a car, you can park it free-of-charge on weekends and public holidays. To park during weekdays, purchase parking tickets for a max. of 90 min. from the nearest 'Tabak' or park in the opera parking (about 10 min by foot away).
Note for English-speaking travelers who do not speak German: the 'C' in the bathrooms does NOT refer to COLD water! The bathrooms have been renovated in a lovely French-style. If you want to take a hot shower, choose 'C' for chaud. 'F' is for cold (froid in French). Finally, being in Vienna you will notice that the WCs in this apartment have that exquisite 'shelf' inside the toilets should you wish a closer inspection of the remnants of your previous meal before flushing it into Vienna's sewage system. Our bathroom even had a bidet (who uses a bidet these days?). Oh, and Vienna is one of those few capital cities in the water where you can drink clean water straight out of the tap. Enjoy!
All in all highly recommended. Just don't book it when we want to stay there! ;-)
