If you are planning a stay in Vienna and you desire to be in a super central location (district 2) but in a residential area, then Igor's apartment is perfect for you. The flat is new and furnished with fine taste, not to mention the fact that is nearby Prater and well connected to the city centre since it's between two different metro stops (U1 and U2 lines) that will bring you to Stephandom Platz, Karlsplatz and so on in a few minutes. Furthermore, Igor is a very kind and thoughtful host, the check-in and the check-out were very smooth.
Really recommended.
