Eva and Michaels flat is absolutely amazing! It's very quaint but still has all the amenities you may need including a washer. The also include lots of little touches to really make your stay feel personal.
We arrived super early in the morning before check in but they gladly let us drop our bags at the apt so we didn't have to carry them around all day. Once the flat was ready they let us know promptly that we could come back and walked us through all the ins and outs of the the flat.
The flat is within walking distance to many sites in the main tourist areas and is very close to public transport making it great for getting to the main train stations and also trips further outside the city center.
Overall the flat is really a great find in Vienna and would highly recommend for anyone who is visiting.
