Marks place was extremely welcoming and the perfect place to stay for a few nights as we explore Vienna for the first time. His apartment is located about a 20 minute walk from the main attractions or even closer if you take public transit. The apartment itself has all of the essentials. The room is perfect for a couple or solo travelers. Bed was super comfy which is always a plus.
Mark himself is very nice and even invited us to a home cooked dinner with his family which was far too kind. He also made us feel welcome and let us hang out with him and his friends when we came back to the apartment. His dad lives in the apartment too and he was kind as well.
Overall the experience was great and we have nothing but good things to say about Mark and our stay in his place.
