Maureen & Sebastian were very communicative ahead of the booking. They let us push our arrival time from 12pm to 2pm, so we could make time for Schonbrunn (coming from Budapest).
The flat was very easy to walk to from the Hbf. metro stop, and we were greeted.
The apartment is a living/kitchen area with one bed and a larger room with the other, larger bed. Though we were two non-dating people, only one bed was made. I found linens and used an extra pillow for the other.
Note: the fridge is rather loud in the kitchen, so light sleepers should use the actual bedroom.
M&S were very helpful with maps and food suggestions in a binder, as well as with toiletries and necessary flat supplies.
We didn’t spend much time there, since we weren’t in Vienna long, but it was a comfortable stay.
