The room is big and comfortable. The only drawback is that there is no shutters, only curtains that do no stop all the light, so bring your night mask if you need total dark to sleep ;)
The kitchen is small but is convenient to have meal !
The flat is well located, not direct in center of the city but is really close to U6 and tram 43, so it's easy to reach the center. And there is a supermarket just down the street so it's really easy !
Ema is very nice and really flexible on hours to move in and out! If you want to spend a fiew days in Vienna, you can definitly come to Ema's with no doubts!
