The shower does not drain well and floods very easily. You cannot leave the water on for more than a few minutes at a time without allowing time for it to drain or otherwise, it’ll flood the floor. This also makes the shower floor get grimy after a few uses. Asked the host to come have a look as we were there for 4 days but we were completely ignored.
The rest of the apartment is wonderful and clean.
The only other thing is, it can get somewhat loud if you sleep with the window open, as you are in city center.
