Roman is a great host and very helpful. The apartment is lovely and spacious and clean. It is about a 10 minute walk to the train station and underground station of Wien Mitte/Landstrasse. It is also close enough to walk into the main city centre. There are some nice places to eat on Landstrasse/Hauptstrasse which is a 5 min walk away. The main street of Marxergasse is quite busy during the daytime but it is quiet at night. The main bed is raised of the ground and requires climbing a ladder to get to it but it is very comfortable. There is a sofa bed as an alternative which we didn't use so can't say how comfortable that is. There isn't a separate bedroom, both beds are in the living room.
