Berns Hotel's official website lists Lady Gaga among the famous people who have been hotel guests, and The Arbuturian independently stated in 2013 that she had stayed there. Neither source discloses the stay date or room.
Lady Gaga stayed at Berns Hotel in Stockholm. The strongest evidence comes directly from Berns: an editorial page on the hotel’s official website identifies Gaga among the famous people who have been guests over the years. Independent hotel coverage published in 2013 also states that she stayed there.
Source conclusion:
The cited sources support a stay at the named hotel.
