This is a great apartment with AIR CONDITIONING a stones throw from one of the best attractions in Vienna: the treasury and armory museum. We had less than 12 hours in Vienna, including sleeping time, and this apartment allowed us to visit a lot of beautiful sights. Also, it was a heat wave, about 100 F, and I was thrilled to see the air conditioning unit in the apartment. I would highly recommend this to anyone. There are a few flights of steps up, so if you have heavy bags, it might be a struggle. Other than that, this place is perfect.
