We stayed at Irina's apartment for three weeks. Irina's apartment is well located, spacious and comfortable. Very close to the Gumpendorfer Strasse u-bahn and the Lidl is downstairs. Also the washing machine was very handy.
Irina is accommodating and quick to respond to any questions.
Whilst we had no issues, there is some street noise from Mariahilfer Gurtel at certain times when the windows are open and there are groups of people 'hanging out' at the u-bahn station.
Overall we enjoyed our stay at Irina's apartment.
