We enjoyed our stay at Bana’s place. It was very cleaned and he kindly offers toiletries and some other stuff in the kitchen just in case. You can make coffee, store fruits and snacks in the fridge or even cook! Bed is a king size frame with 2 individual mattresses. There are plenty of pillows and blankets. Clean towels, an iron, a safe and a very nice storage setting closet.
There is a mobile A/C unit in the dining room and you’ll have to fix the exhaust into the window. There is also a fan available that you can move to the room to sleep better since the summer temperatures in a Vienna are really high.
Supermarket is 2 blocks away and it’s open until 6pm. There is a shopping mall nearby. Public transportation from the apartment didn’t work for us, since the train station is not that close.
There are a few walking distance attractions and a few ok restaurants. But you definitely need to take an Uber to visit most of the touristic sites in Vienna.
