Maureen and Cloud's flat is very centrally located and clean.

The weather was quite hot on the day we stayed in Vienna and the flat did get a bit stuffy. There is a fan in the flat but no AC. It wasn't a huge issue for me personally but you may want to take into consideration, depending on the time you're planning to travel to Vienna. As someone has already mentioned, the bathroom is a bit small so you need to be ok with that as well.

Maureen and Cloud met us at the flat and were very responsive throughout.

Overall I had a pleasant stay at their flat.
