Splintered corners, giving The Shard in London its iconic multifaceted look, are now also responsible for letting guests of Europe’s tallest hotel see into the spaces of their nighttime neighbors.

Having sent a reporter to spend the night, the Financial Times confirmed guest reports in a snapshot: a series of glass panels standing out from the structure have turned into a series of accidental mirrors, giving room-with-a-view a new meaning in the context of this building.

During the day, visitors to the Shangri-La can see out in nearly all directions, but at night with inside lights on they also get an uninvited sneak peak back into adjacent bedrooms. Designed by Renzo Piano, the famous building may not be as problem-plagued as its car-melting sibling but it certainly has some issues yet to be resolved.

The solution so far offered by the hotel seems somewhat incomplete – they are notifying guests of the issue and advising them to use curtains. Still, not everyone will remember to take such steps and many will want to leave their curtains open, since they came for the lovely views in the first place. In the end, one is left to wonder how no light modeling of the building revealed this potential problem (image above by Patrick Collins).
