This apartment was lovely, a very clean, small but cozy place. The location was excellent, a few minutes away from public transportation (metro, buses etc) and about a half an hour walk to 40 minutes on foot to the city center (Opera state House - Hofburg palace etc). The directions to self check in were very clear and were sent to us via message. The overall experience was great, I would totally recommend this facility for future travellers, especially couples.
