We liked the apartment. It is very open and much daylight enters because of the big windows. It was clean as well and near public transport and a lot of supermarkets. The bathroom is a bit small but contains everything you need. Vienna is a big city and the apartment is located quite west of the main sights. It is possible to visit the sites by foot or bike as we did but we can imagine it will be easier to use public transport if you are not able to walk as much or don't like walking that much ;) Cristian has made a little folder with information to get around which is very useful. Communication with Christian was really easy and he is a great host!
