The apartment was perfect, very near to the ring (the boulevar that sorround the center of Vienna) and with a public bike station very near (super handy public bike system in Vienna). It was ver big, with a big bed and two wardrobes. The living was also very big, with a coach and a table to eat. The kitchen was small but very practical, another table there too. The windows are good, as they blocked very well the traffic of the nearby street.
The host was very nice and responsive, as they were out of town, they told a friend to come and welcome us, which was very well appreciated by us. :D
I would recommend 100%
