The place was lovely and the location is perfect, we had no issues at all finding the apartment and getting around
The bed is comfortable and the kitchen had everything we needed
The only little issues that we had was the internet (it kind of reebooted very frequently), the water heater didn't heat enough water for two showers a day and the heating didn't work (but that wasn't a problem as we had the little heater on when we needed)
We loved staying in Vienna in this apartment
