I would highly recommend this apartment! I currently live in Vienna, but stayed here when my family was visiting. The apartment is located in one of the best areas of Vienna (3rd district, a short walk from the center) with a beautiful view of Stadtpark and only a block from the metro (U3 & U4) and S-Bahn (with access to the airport: S7 in 30min). The apartment is decorated beautifully with attention to details to everything you need for a very comfortable stay. We even used the kitchen and washing machine and all appliances were of good quality. There was excellent communication and easy key retrieval with a lock box (they even sent an SMS offering to be there on arrival). The apartment slept 4 adults comfortably.
