The Aelpli Bar is located in the middle of beautiful downtown Zurich, the walk to the bar was very cool.
We ran into some issues with the later check-in time, but were saved by the public access lockers at the main train (9 CHF / day).
The beds are really comfy, and the room is cozy.
Be warned, there are high door thresholds that are easy to miss and trip over (speaking from experience! Haha).
The music is definitely easy to hear from the room, but if you are a heavy sleeper, you'll be fine.
Overall, we greatly enjoyed the visit and would do it again!
