We were mostly in contact with Aida, the person responsible for handing over the key for the apartment, but both she and Elma and Medo were super friendly hosts and even asked us once we had arrived if there was anything they could do to make our stay better. Apartment was lovely, very spacious and cozy. The location was great for us since we were coming to Vienna to see a concert at the Gasometer. Also, there are two grocery stores a short walk away and everything you need at the Gasometer. Would definitely stay here again!
