A great place to stay in Vienna. Yu is super friendly and accommodating, and communication is great with her. She responds quickly, and should there be anything you need, she makes sure you get it asap.
Bedroom faces the courtyard, so it's very quiet, great for anyone sensitive to noise when sleeping. The bedroom is cold, however, and Yu provides a separate heater for the room which in the winter months does the job, though you may need to warm the room up some before settling to sleep.
Everything else is accounted for. No TV but that was no issue for me, and I suppose won't be an issue for a serious traveller/working professional.
Location is great, too. Very close to major supermarkets and a pharmacy.
All in all, very happy with this place. Thank you, Yu!
