The apartment is located on groud floor but it is in a higher position respect the street, the kitchen is enough for 2-4 people, we used the kitchen to cook our meals, breakfast and we used the oven too, the table in the lounge can be used from 4 person, internet works fantastic, the television is big and the sofa is good to relax seeing some movies or other, it is a sofabed so it is a little hard.
The bathroom is really good but pay attention to the bath tube because it is very slippery when wet with water or with soap.
The bedroom is perfect for 2 people (the other 2 will use the sofa) but it is warm, the bed and pillow are very soft (we used 2 of them to sleep well).
The main station and the center is very close, remember that on sundays all is closed, only a little Interspar is open on the central station, so if you need to buy souvenirs or food to cook in the apartment you will have to buy days before sunday.
In July the apartment was too warm for us, we used the air blowers but two night it was too hot, we mitigated this problem, opening the windows when we were at home and closing them before to slip.
If you wanna park the car there, you will be able to do for free from monday to friday from 22:00-09:00 and on holiday, saturdays and sundays all day.
From 09:00-22:00 on monday-friday you will have to pay, you can buy tickets from 30m or 1h in the tobacco shops, if you will use more tickets (for example to stay 2 hours) both must have the same day and time of starting.
Vienna is very beautiful and the apartment is in the right position.
