This little apartment is a lovely space with a great location in Vienna. The bed was very comfy and cosy and was made even more welcoming by the addition of a lovely Mozart chocolate on the pillow. The whole apartment was exceptionally clean and the shower was really powerful. Check-in is digital by a code box outside the apartment. Whilst this is practical, I don't think it is safe for two reasons. Firstly, it's much easier to get a hold of a code for an apartment than it is a key. Secondly, the door can be opened by anyone who knows the code from outside even if locked by someone else from the inside.
Thomas was a good host, very quick to respond to any messages and we were able to check in a little earlier than the stipulated "3pm check-in" which was very considerate. I do want to stress however that if your German is non-existent then I would perhaps suggest staying somewhere else. All of my correspondence with Thomas was in German which for me was absolutely no problem at all however, it did mean that during our stay there was some miscommunication with the next Airbnb booking after us which I can only imagine arose from the language barrier.
Otherwise, this apartment was perfect for all our needs and we had a lovely time in Vienna.
