Due to Covid-19 restrictions, I needed to stay an extra day. Gregor was very relaxed and accepted without any problem. Best price benefit I have had anywhere. Excellent location, great for runners lovers, great for people who wants to feel a piece of Vienna, and perfect for a romantic time in the city of love. I will definitively go there again. Even during Covid-19, Gregor was very helpful with anything, always respecting the safety measures. The apartment has a zero-contact system that allows you to get the keys without meeting anyone in person. I loved that. No need to risk. Five stars to the place.
