Cheapest option we found for a last minute booking in Zurich, about 10 minutes to the train station on an easy walk.
We checked in with a friendly staff member, which is actually located in a convenience store as the ground floor. He gave us the code to our room, located on the top floor (#51). Unfortunately there is no elevator. This had a roof top balcony overlooking the city which was quite nice!
Bed was comfy, bathroom and shower were clean, the room came with a portable AC unit to help at night. Honestly exceeded my expectations for the cheapest double room available in town. We were able to grab food around the area, lots of options.
