The entire apartment was beautiful and clean, and the kitchen and bathrooms very comfortable. The room itself was somewhat small, we needed to make some space to be able to lay down our suitcase. We woke up quite a few times during the night - mostly because of the light coming in from the apartment's hallway, when other guests returned and turned on the light.
The location of the apartment is great; with a ~6 minutes walk to public transport, or about ~20 to the city centre. Alina and Roman communicated very clearly about everything and had great recommendations for our stay in Vienna. Overall a nice place to stay, but we didn't sleep very well.
