Even tho I was not able to visit their apartment (covid), I felt perfectly taken care of by the owners. Whenever I had a question, they replied pretty quickly and with all needed details. Also, I shared with them my ideas of how I want to spend time in Vienna, and they gave me a lot of tips, of where to eat, or what to visit. Really great people. I'm just sad that I couldn't manage to visit their apartment because of me being sick... :( But I'm highly recommending their apartment!
