Martin's apartment was the perfect base to explore Vienna from. Good bed, very quiet, 2 supermarkets that are extremely close, just outside the building (Hofer and Billa). The kitchen was well equipped with everything we could need and we really appreciated having a lot of towels for the bathroom.
It's very well connected with public transport, and you can use Uber easily without breaking the bank.
We liked Vienna very much and can't wait for our next visit. we will surely try to book Martin's place again.
