I stayed in 3 Airbnb locations during my vacation from Budapest across Austria and this apartment was absolutely my favorite of them. It is literally one block from the Taubstummengasse Metro station (just walk down Mayerhofgasse across the street). This is just 2 stops from the city center metro station.
For a studio apartment, this place was very bright & sunny and larger than I expected. Yes, you do have to walk up 4 floors to get there, but I loved hanging my head out the window and looking down the street from up there.
One of the best parts was that there is a laundry washing machine in the apartment, with drying rack AND laundry soap you can use! That was really helpful.
The keys are done thorough a lock box system, and I never met the host. But I have no problem with that. I really loved staying at this apartment and would absolutely do it again!
