Isi was a Perfect Host!!! She met us with the keys even we arrived very late! The house is situated very near to U-Bahn station and it takes only 10 mins to get the center of Vienna! The flat is comfortable, you have everything what you need and it is warm inside. We were staying for month and really had know even one problem!!! I would highly recommend this flat!!! Hope to come back again, thank you Isi!!!
