This place was FANTASTIC! We've stayed at many apartments throughout Europe and Laer Vienna's combination of location, convenience and space makes it one of the better places we've experienced. This place is extremely clean as well.
The location is perfect for a first-time visitor since it's directly on a main bus line and within walking distance of some major attractions. At first, I thought this might mean that it's on a busy, noisy street but we were pleasantly surprised to find that it was rather quiet for city living. Additionally, there is far more space at Laer Vienna than you typically find in European apartments. The keyless entry meant one less thing to lose and the main entry opens directly to the street, making it quite convenient for coming and going.
There was a very informative book of notes prepared perfectly for an English speaker and it was quite helpful for determining what we were going to do during our stay. We had a lot of fun checking things off of the list of recommended activities.
Overall, I would highly recommend staying here. It is a great space with a perfect location for any tourist who wants to live like a local while in Vienna.
