Our stay at Lia's apartment was absolutely great: a flat with a lot of space, very clean rooms, bathrooms and a modern kitchen. The location is perfect as it is silent as it is on a side street, but also very near to the next underground station, from where you can go everywhere in Vienna in minutes.
The communication with Lia was also perfect, very clear instructions, very responding if we had any questions and generally very nice and respectful.
To sum up: we can totally recommend Lia's apartment and we would give 17 stars if we could ;-)
