Spanish police are investigating the death of a 48-year-old woman who fell 15 floors from a hotel balcony in Benidorm.
Donna Sharp, from Barry in the Vale of Glamorgan, died on Sunday, 14 November while on holiday in the resort.
Her 25-year-old daughter Angel, who also lives in Barry, told BBC Radio Wales that her death was a "tragic accident".
"She was unique and I loved her to pieces," she said.
Angel said she received a phone call in the early hours of Sunday and "it just blew me away".
"Nothing can prepare you for that phone call, nothing. I don't think I'll ever get over it, never.
"We're in a total state of shock."
Ms Sharp fell 15 floors from a balcony at the Aquarium II hotel in the Playa de Levante area of Benidorm.
It is a high-rise hotel that she knew well after staying there on holiday previously.
Her family said she had been out on the last night of her holiday with her partner.
She became tired and decided to return to the hotel room early to start packing ready for their journey home the next day.
But some time after returning to the hotel, she fell to her death.
Police are investigating exactly how she died but her family do not believe there was any foul play.
Angel added: "It was just a tragic accident and I can't believe she's not coming back."
The family have been in close contact with the British Consulate in Spain and have been told a post mortem examination was carried out on Monday.
They are now hoping the Spanish authorities will release Ms Sharp's body some time over the next day or two so they can fly her home and prepare for her funeral in Barry.
Angel said she had told her four-year-old son that his grandmother had died.
"She was the most amazing nan I could have ever asked for for him. I think it was just totally tragic - tragic circumstances. She's gone too soon," she said.
"Nothing can describe her - she was so unique. Anybody that knew her, you couldn't say a bad word about her, she was such an amazing person. I loved her to pieces.
"She was all for her family. All for me, my nan and my son, and she would've done anything for any of us."
Donna's mother, Patricia Sharp, said: "She just wasn't my daughter, she was my best friend too and she was with me all the time.
"She was just a wonderful girl. Everybody loved Donna, everybody."
