The apartment is really cozy and nice. It is located just 1 ~ 2 min. walking distance(110m) to Keplerplatz U-Bahn station and 15 min from Wien Hbf.
Even before I get to the city, the host sent me messeges on good places in Wien.
The room was suitable for the travellers. Especially the bathroom, clean of course, water pressure is very strong, well-designed, and with a poweful hair dryer.
I can tell you lots of merits like an up-to-date door lock system, a good dressing table, washing machine. But the most touching point is the responsibility. The host always response immediately and try to solve your request.
