Roland is a very good host. He responds quickly on messages, is flexible and interested.
Rolands appartement offers good ingredients for a nice stay in Vienna. Firstly, it has everything a couple needs for a short citytrip. It even has a washing machine which you are free to use. Moreover, for 5 euro's per night you can use the parking place in front of the appartement. Secondly, it is located on a perfect spot. The Spar and Hover are closeby same as the tramstation, metrostation and trainstation. From there you reach Vienna's first district within 5019 minutes. Thirdly, it is located in a very nice neighbourhood. It is close by is the Donaucanal. An eveningwalk is very nice over there. Furthemore, in the summertime there were nice bars where you can have a drink.
Concluding, I would recommend Roland's appartement due to his hospitality and the location of the appartement.
