After our flight to Vienna was delayed significantly so we had to check in at around 1.30am in the morning but this was no problem as the hosts had provided checked-in instructions in advance which were very clear and we were able to immediately enter the building and apartment and get some rest. What a great system they have for quick entry and check-in! The apartment is very very clean and comfortable and upon waking to look for breakfast, cash, groceries and a pharmacist, I followed the details from the guidebook inside the apartment and went for a walk and everything was as stipulate and very close (practically outside the front door!): ATM, SPAR supermakret, Apotheke, Trams and Cafe! Additionally, we found downtown Vienna to be a few tram stops away which was no problem at all to get to. We were very happy and wish we had stayed longer! Thanks so much!
