Very little apartment but with lot of room for two. Not for people who fear to climb steep stairs or a ladder. A really nice place to stay for a few days in Vienna.
Joseph was very welcoming, and gave us a lot of very good advices. The appartement is really well located, some 12 minutes walk (or 2 metro stops) from the Westbahnhof (direct connection to the airport) and shopping street Mariahilferstrasse, 2 minutes from the metro line.
A nice place to stay and we recommend it!
