Our stay in Vienna didn't start off very well, because unfortunately our host had forgotten about our arrival due to some special event at work and then, when he finally arrived, he was missing the front door key... still, he was very nice and about an hour after our arrival to the front door, we finally managed to get into the apartment. The apartment is very nice, spacious and well furnished - there's pretty much everything one needs for a holiday. The balcony is amazing - really safe for children, with lots of space. The apartment is on the 7th floor, but the lift only goes until the 6th floor, so it's not really appropriate for people with limited mobility, but it was OK for us. Overall we were happy, we only wished the arrival had been smoother.
