Hotel guests at the recently opened Shangri-La hotel in the Shard in London have been warned to close their blinds at night as they may be visible to other guests.
News emerged that some glass panels at the hotel can act as mirrors once the lights are turned on, meaning that they are capable, in some cases, of offering a glimpse into neighbouring rooms.
The potentially embarrassing feature of the rooms was highlighted by the Financial Times, and is as a result of glass panels that protrude several metres beyond the building's corners to give it the appearance of a "shard of glass".
Some rooms also overlook each other because those at the corner of the building are at right angles.
Darren Gearing, the executive vice-president and hotel general manager, said: "As a building created largely from glass, all guests can enjoy spectacular views of London from floor-to-ceiling windows.
"In some rooms, due to the unique shape of The Shard, guests may be able to glimpse into a neighbour's room. For this, blinds are available for guest privacy."
The 202-room hotel in the 1,000 ft high Shard opened earlier this month.
