I had another stay there a few weeks back as well. Had asked my concierge to request a rooom away from the tram stop. When we got to the room it was one of the suites that has the small bathroom w/ no tub (very tight bathroom) on the tram side. I had them move us. I'm really on the fence with this hotel. Everyone here loves it; I find it tolerable.
As for Uber, we didn't know Uber was a thing in Prague so we used Bolt. Same theory but also very inexpensive.
