Princess Diana stayed at Hotel Byblos in Mijas, the Costa del Sol property that later closed, was transformed and reopened as La Zambra Resort. La Zambra’s official history names Diana among Hotel Byblos’s A-list guests, while independent travel and Spanish media accounts corroborate the hotel relationship.
Celebrity Hotels classifies this as a verified stay with evidence grade A. The historical name matters: Diana’s visit belongs to the Hotel Byblos era, not to the modern La Zambra brand that opened decades later.
The short answer
La Zambra’s own published history says the resort was formerly Hotel Byblos, which opened in 1986 and attracted guests including Princess Diana. The hotel describes Byblos as a private retreat for prominent visitors during the 1980s and 1990s, then explains that the closed property was transformed and reborn as La Zambra Resort.
The Standard independently identifies the same succession. Its 2024 review says the site was home to the Byblos in the 1980s, names Princess Diana as a guest, and reports that the hotel closed in 2010 before reopening as La Zambra in 2022 after an extensive renovation.
Vanity Fair España provides the most specific timeline. Its 2023 feature reports that Diana went to Hotel Byblos in Mijas with two friends in 1994. That year is useful historical context, but no exact check-in date, checkout date or room is supplied in the accessible report.
What the evidence establishes
The first-party hotel history establishes two linked facts: Princess Diana was a guest of Hotel Byblos, and the former Byblos property is the historical predecessor of today’s La Zambra. Independent publishers support both the guest claim and the property continuity.
This is not an inference based on a photograph near Mijas or a generic association with the Costa del Sol. The current hotel itself names Diana in its account of the former hotel’s guests. The Standard and Vanity Fair España separately identify Hotel Byblos and describe her as a guest or staying there.
The evidence supports an accommodation relationship rather than only a restaurant visit, public appearance or event. The official history places Diana within a list of hotel guests, and Vanity Fair España explicitly describes her choosing the Byblos as a place to withdraw with friends.
Hotel Byblos and La Zambra are not interchangeable names
Hotel Byblos opened in 1986 and operated during the era connected to Diana. It later closed. The current property opened as La Zambra in 2022 after a substantial transformation of the former hotel.
It would therefore be historically inaccurate to say Diana stayed in a modern La Zambra room or used its current amenities. Celebrity Hotels attaches the evidence to the existing La Zambra listing because the hotel’s own history presents it as the rebirth of Hotel Byblos. The article preserves the name that applied during the visit.
When did Princess Diana stay?
La Zambra’s official account places its famous-guest history broadly in the 1980s and 1990s and does not publish a date for Diana. Vanity Fair España dates a reported visit to 1994 and places her at Hotel Byblos with two friends.
Celebrity Hotels therefore treats 1994 as an independently reported date, not as a date supplied by the hotel or a public reservation record. The evidence reviewed does not show whether Diana visited only once, how many nights she stayed, or whether every later anecdote about the trip refers to the same visit.
What remains uncertain
No booking record, room number, staff log, exact stay dates or duration is public in the sources reviewed here. The sources also do not establish which parts of Hotel Byblos survived the transformation or whether a historical room has a modern equivalent.
Vanity Fair España recounts a paparazzi story connected to the 1994 trip. That anecdote is unnecessary to verify the hotel stay, and this article does not reproduce private or copyrighted images. The verdict rests on the official guest history and independent written corroboration.
The evidence does not establish a visit under the La Zambra name. Since Diana died in 1997 and La Zambra opened in 2022, such wording would confuse property history with brand history.
Why this receives grade A
Grade A requires direct first-party evidence and a precise relationship. La Zambra’s official history names Princess Diana among Hotel Byblos’s guests and explains that Byblos was the property’s former identity. The Standard and Vanity Fair España independently corroborate the stay and succession claims.
The grade applies to the historical Hotel Byblos stay at the property, not to a modern La Zambra stay. Keeping that scope narrow makes the conclusion stronger.
Evidence verdict
Verified: Princess Diana was a guest of Hotel Byblos in Mijas, the predecessor property that was later transformed and reopened as La Zambra Resort.
Independently reported: Vanity Fair España dates a documented visit to 1994. The current hotel’s official account confirms Diana as a guest but does not give a year.
Not verified: The public evidence does not establish exact dates, number of nights, a room or suite, multiple stays, or any visit under the La Zambra name.
The result is a high-confidence historical stay whose former-property identity is documented rather than assumed.
