Griechen’s flat was an awesome choice! We were only blocks away from Stephansplatz, and less than a block from the übahn which was great for traveling around. Griechen was very responsive and clear with check in and check out directions. The flat was very well kept and even had added amenities such as a washer/dryer and welcoming family room. I highly recommend choosing to book with Griechen if you are visiting Vienna!
