I had read the review's of Lisa's apartment and after our stay I would say that it is one of the best place that we have stayed.
The apartment is tastefully and well furnished, having all the conveniences of own home.
There is free parking on the street for the car and public transport (bus stop) is 2 min of walk from the house. By bus it is 10 min to the metro station and as the bus runs every 10 min or so it is very convenient.
Lisa is a gracious and welcoming host and I would highly recommend her apartment for anyone who plans to spend a few days in Vienna,
