Ani was very helpful and friendly. The wifi connection worked well and allowed easy access to conference meetings. The apartment was about 20 minutes from the city centre by foot or tram. Which made it reasonably easy go get to all attractions.
The room was comfortable and a good price if you plan on being out for most of the day.
The blanket on the bed was just too small for 2 people to sleep with but it was luckily quite hot.
The location and the building is in an older less well kept area of Vienna and is different to the glitzy, manicured buildings you will see everywhere around the city. It seems as of previous visitors were discurtious and the clothing rail and basin plug were amiss.
