Karim was incredibly supportive and nice. He always answered our questions and helped us whenever we need his help. (Eg call a reasonable taxi price for us) facilities and equipments in the room are fully equipped.
Locations were fine too. Connected to U3, its one station away from Westbahnhof which is one of the large train station/bus stations. 2-3 stations away from the long shopping street (mariahilfestraße) and around 5-6 stations from Stephanplatz which is the city centre.
The rooms are really clean too. A little too small living area but good enough for a 2-persons dining.
