Plamen's apartment was super convenient to access many areas of the city.
Although it is really close to a main train station (5 minutes walk), it is really quiet as it is situated on a side street.
If you walk in the opposite direction there is a metro station in less than 5 minutes, as well as a small supermarket and some cafés and restaurants. 3 stops on the metro and you're in the centre of Vienna - so easy!
The apartment was a nice size and the kitchen had everything we needed and there is a separate toilet and shower room. It's on the 4th floor in a block of apartments and there is a (small!) lift which goes from floor 1, so there are only a few stairs to manage.
A great location to explore Vienna from!
