Goldhotel has very good mattresses and beds, a Lift (my daughter and I were at third floor). We spent there five nights. The bathroom is small but there are what you need.
No possibility of breakfast (28 August - 2 ) September there is no kettle, and not even a bottle of water.
Tram 21 runs along the street of the Hotel : with two stops you reach Subway U5. Timetables and directions are written on the Signs for Bus stops. The area looked safe.
