Harry's apartment was lovely and spacious with everything you need. It's really close to Wien Mitte train station and only a short walk through a lovely park to the old town.
Everything in the apartment was clean and tidy. We didn't much time there but the kitchen seemed well equipped.
We called Harry when we arrived at the apartment and met an associate of Harry's who let us in and showed us around.
I would recommend it for anyone exploring the city for a few days.
