The apt has a good price/quality ratio, but unfortunately I was living there during the period of a heatwave in Vienna, with +32С outside and 29C inside. Apt is on sunny side, so during the day it was extremely hot inside. The only small fan available was not helping at all.
Also keep in mind: house got no elevator and apt is located on high floor, so if you have heavy luggage will have to do some sports activities.
The internet was not working properly in the mornings and evenings - don't know why, had to work during that time from cafes or library.
Overall apt has great location, has all necessary tools inside, so in other time but summer - would definitely visit again.
