The best thing about the apartment was its location, which was very convenient to access to major tourism places by metros and trams. Also there were several grocery stores and pharmacies we only had to walk for 1 to 2 minutes from the room. The host, Christoph, was pretty nice and supportive; we were always feeling secure because he was very fast to answer our questions before and during the stay. The only concern we felt about the place was the lack of air conditioner because it was pretty hot in Vienna during our stay and we brought our 9 months old baby; as far as I know it's quite difficult to find an apartment with an air conditioner in Vienna though... Anyway this apartment was a very good deal!
