We had a very pleasant stay in the apartment. It was very clean and has everything you need for a stay.
The building is easy to find, however there isn’t great lighting so make sure you have a torch if arriving in the evening!
The building/area felt safe and was around a 25 minute walk to the centre of Vienna. Transport links are great. The area itself has places to eat and shops, so you can explore this area as well as the city centre. Do be mind full that grocery shops close quite early in Vienna so if you need food/drinks etc for your stay, get them early.
Communication with the host was great.
Only downside was that we weren’t able to check-in before 4pm and we arrived in Vienna in the morning.
