Hilton Worldwide has signed a franchise agreement with Grupo Aventia for its first Curio Collection hotel in Spain. Following restoration work, the 33-room Gran Hotel Montesol Ibiza will open as part of the collection this summer. The hotel, in the historic centre of Ibiza town, was the first purpose-built hotel on the island when it opened in 1933. The building, which has been recognised as a site of heritage and cultural interest by the Spanish Ministry of Culture, has served different purposes over the years, including housing a military barracks during the Spanish Civil War. Hilton currently has one Curio property in operation in Europe, in Hamburg, Germany, and the Curio Collection pipeline currently counts more than 80 hotels in various stages of development across the globe.
