I had a pleasant stay at this lovely apartment in Vienna. It is perfectly located for anyone who likes walking through the city rather than taking public transport, and is well connected to three U-Bahn lines if you need to travel further afield.
The apartment itself is spacious and gets lots of light. I had some difficulty working the hot water to the shower, but only on some occasions (other times it was fine!). Benjamin was very helpful and communicative. I would recommend Tomasz's apartment to anyone coming to Vienna.
