I highly recommend Marie's place.
The first reason is that Marie is a fantastic host who is willing to go extra miles to help her guests.
We were arriving in Vienna on a Sunday morning, and Monday was a public holiday in Austria. As foreigners, we had no idea what that means in Austria. Marie got in touch with us ahead of time and reminded us that stores will be closed during our stay there on Sunday and holiday. She offered to do grocery shopping for us. Although we did not ask her to do it, we are extremely grateful about it.
Staying at Marie's place makes you feel like not only getting a great place to stay, but also getting concierge service. Marie prints her own tourism maps and gives out to guests. We've been to Airbnb where hosts give maps to guests, but Marie goes one step further by providing her own maps to guests. It has all the information you need for a visit to the city of Vienna, including main attractions, public transportation maps, restaurants and bars, etc. It is the ultimate guide for us. Also, you can always contact her for questions.
The second reason is that this place is extremely clean and cozy. The cleanliness is impeccable. Trust me, you will never find a place as clean as her place.
One last comment: the guests before us seem to have left a pile of dirty dishes to Marie upon checking out. It is unacceptable. While I strongly recommend this place to you, I also strongly urge future guests to respect the host by cleaning your dishes, taking out trash, and leave her place the same status as you check in.
Overall, I highly recommend Marie as a host and her place as your choice of lodging during your stay at Vienna.
