The communication with Walter was very fast and very efficient. Upon arrival his friend Thomas showed us the appartment and gave us very knowledgeable and useful advice on Vienna and our immediate neighbourhood. The appartment was clean, spacious, stylish and just perfect for our purposes (city trip with 2 teenagers). the WiFi took some minutes to "welcome" us, but then worked perfectly. everything was as described and as we had hoped it to be. the location of the place was just perfect. definitely a place to go back to when in Vienna.
