I really enjoyed my long-stay in the very central apartment. Carolin helped me through the booking process and was always available for any questions/help.
The apartment was very clean and everything was stored away so I had plenty of space for me and my belongings.
It was both modern (in decor style and new appliances) and traditional (with the high Viennese ceilings), a perfect combination.
Furthermore, the location was perfect, a very short walk to the Opera, and right by Karlsplatz and the many embassies. If the short walk isn’t for you there are 3 tram lines and a U1 metro that will take you directly to the centre.
I highly recommend Carolin’s apartment, and will be delighted to return when possible.
