We stayed at Johann's place for a couple of nights over the Christmas period. It was a really wonderful stay at a beautiful little apartment that had everything we needed. We were very happy to have a kitchen fully stocked with utensils and other useful items to facilitate our home cooked Christmas dinner.
The location was invaluable for getting everywhere we wanted to go. A quick 2 stops on the train between the airport and the apartment made airport transfers easy (& cheap at 4-5 euro each!). We also had buses, trams and metros all very close making trips to the city centre and other points of interest really easy.
The bed was a little hard for us but still slept comfortably. Only other recommendation would be to darken the curtains so we can sleep in more as we're on holidays :P
Thank you for having us! Very happy with our stay :)
