I like how Aleksandar response is fast, and was available for check in.
The location was relaxing, in-front a park, and nearby 2 Grocery stores and restaurants.
However, we have some points:
1. We wish it was self check in, because we wanted to arrive late.
2. We wish you provided 2 keys, because we are a family of 4.
3. The bathroom was split into 2 different rooms, which we never encountered, as the sink & shower was in a room, and toilet was in another ! This was difficult for hygiene purposes.
4. The portable AC was small, and barely providing cool air for the room, and people on sofa bed in the kitchen/entrance was still warm. Also, the windows had to be open to blow hot air from AC, so we had to open windows, and it was a mix of hot and cool air. I recommend finding a better solution.
5. Good that he provided an fan, and appreciate it if provide a second one.
6. The bed was uncomfortable to lay in the middle, because it was hidden 2 small beds, and had to sleep on the sides.
7. I wish he provided clear instructions for parking payment, as this was my first time in Vienna, and had no idea need to go to Cigarette store (close at 6pm) or gas station( far away ) for manual payment cards/slip. Parking spots were available without any issues.
