We stayed in the apartment for one week and before and after the rental period, the communication with Claudia was excellent. The location is perfect for visiting Vienna, we know that as we lived in the 6th district for 9 years. The interior is well designed, modern and very clean. It is also relatively quiet as it is not close to the street and there is no need to take stairs or elevator so very convenient. It can be a bit dark, but that is an advantage especially in the hot summer period and the room stays cool. There is enough light however. We can certainly recommend this.
