We stayed here for 3 nights during a trip to Vienna in Feb. Other than the fact that the apt matches all the descriptions, it was very well heated during the cold month of Feb. We had to request a small blanket because my husband is very tall, and Andreas was very accommodating to have someone dropped it at the door. Andreas is a great host and always replied to my messages in a timely manner.
I would highly recommend this airbnb, especially in the summer month where you can use the balcony.
Thanks for hosting us!
