Diana's place is situated in an ideal area to stay in Vienna (it's only 3 minutes from St. Charles' Church, and 5 from Karlsplatz. There are a lot of shops, restaurants, coffee houses and bakeries in the vicinity). You have also bus and tram stops in front of the building that will take you to all the main attractions in Vienna.
The kitchenette is quite small but there is enough space to prepare a dinner.
The bedroom is very spacious.
What was really great about Diana is the fact that she let us stay as long as we needed on the last day (we had a bus at 11 p.m., so it was very kind of her).
The room is on the last floor, so at night it can be a little cold in the winter, but Diana provided warm blankets, and we had warm clothes, so we managed.
I would definitely recommend this room for people who would like to live near the city center.
