We had a good stay at Daniela's place and she was a very responsive host. When we found areas that were not dusted/cleaned she arranged for the housekeeper to come by and clean them up (important for me and my son who have dust allergies).
Only thing to mention is that in Vienna ACs are not common so it gets really hot in the night (you have fans but they can't make up for ACs) and if you want to sleep on an open window you will hear the trains in the Westbahnhof station. That's the tradeoff with being so close to the station, otherwise location is great for commuting.
Overall, good value for money and Daniela is a great host!
