Big thanks to Larissa and Mike for the pleasant stay! I arrived early in the morning, and the hosts checked me in at that time. Besides, they waited until I figure out the metro system and then showed me the stations that I should use. The room was beautiful and cozy, and those two dogs were really sweet and friendly!
The house location is quite good; you can easily get to the main Vienna sites by metro or bus, and the stations of both of them are close enough. It was fine for my short tour to enjoy the city. I recommend staying in this place :)
