Hostel Westbahnhof 

We booked two rooms with this hotel since four of us travelling together. Upon checked in the reception personnel told us bottle of water inside room is free. We do not find the water in both rooms told her and she placed it in both rooms. Did not had breakfast here but after breakfast time if you come back early in the evening you can have free tea, coffee or hot chocolate. The only issue with our room is shower only have half size door so the floor is wet after shower. Since the train station is also a shopping mall so you can buy everything you need. Arrived at late evening we walked around from train station and had our first Vienna hot dog.
