Maria responds quickly to questions and directions were easy.
Little touches in the apartment made me feel welcome.
The apartment is modern and has everything you could wish for. There are even umbrella's.
There was a problem with the internet connection but it was solved quickly and adequately. It's especially when something goes wrong that you discover whether your host is helpful, and in this case Maria definitely was.
The location was very good, almost at the tram stop (though it might be a bit noisy at times if you are a light sleeper) and everything around the corner (small restaurants, supermarket, etc).
I loved the bed. Very comfortable.
Because the apartment is on the ground floor, it isn't very bright, but since I was out most of the time that didn't bother me much.
All in all a good experience and a wonderful starting point for exploring Vienna. Great city! Loved it!
