Martin's place is as described and in the photos, it is in a quite neighborhood with close proximity to the Wien Mitte and other land marks. There is a supermarket close by. Check in was easy, please make sure you are opening the right lock box, I tried to open the wrong one :) Martin was quick to communicate and point to my mistake. Check in and out time are generous, most places ask you to check in after 14:00 and check out before noon. Thanks Martin.
