Marie-Therese was very welcoming. Due to a mix up in bookings, I ended up staying at her larger apartment in the same building thanks to her kindness. Her initial explanation of the surrounding area and knowledge of events in Vienna were very useful for us planning our time there. As for the apartment, it was spacious and though there was a wifi problem, she resolved the issue quickly. The apartment is located close to the city centre and the ring tram; it was a nice stay.
