We spent two nights at Anna's flat, and although we didn't get to meet Anna, she was very responsive through messages. We were able to self check-in very quickly with Anna's clear instructions. The flat is located only a few minutes walk from the metro station, providing very easy access to the main city centre. The local area is just on the outskirt of the Schonbrunn Palace grounds and has a range of options for breakfast and lunch.
Our room was bigger than we were expecting and very clean, with lots of storage options. The rest of the flat was also very clean and decorated very stylishly. Highly recommend!!
