Elxe is an extremely helpful and responsive host, who was quick to share relevant local knowledge any time I had a question.
The apartment is fantastic, it's comfortable and has real character, and the view from the roof is incredible. It's within walking distance to the centre, and there's a range of public transport options just a few steps outside the door. Our family group of 2 grandparents, 2 parents, and 2 kids (4 and 7), felt very comfortable and welcome there.
Vienna is a gorgeous city, and our stay at Elxe's place made the whole trip even better.
