I stayed at Guillaume's place for almost two weeks. Everything went very smooth: the check-in and check-out nd overall communication during the stay. Guillaume was easily accessible and very resourceful; he is a great host by all means. The flat was very clean, nicely renovated and equipped with everything that one would require. I like the neighborhood, the building was literally a few steps away from the main street and tram stop and shopping, especially the farmers' market was super. Easy access from / to airport and all transportation modes. Unfortunately, the weather was cold and I did use the balcony, but it looks nice. When I come back to Vienna, I will definitely stay at the this place.
