Looking at the facade of the Spanish country house where Les Cols Pavellons, Girona, is based, you might think this is a lovely but nothing-out-of-ordinary place. Nothing more wrong! The historic building hides five high-concept glass rooms that feature architectural design out of this world.

The rooms are entirely made of glass: walls, floors, roofs, and even some furniture. You might have to sacrifice your need for privacy for this hotel, but the unique design is worth it. It blends the line between the outside gardens and the indoors, inviting the green surroundings inside your room. Each room comes with a private bathroom and your own heated onsen bath (all glass, of course).

Despite its small size, the hotel is also home to a 2-Michelin-starred restaurant. Les Cols, led by chef Fina Puigdevall, serves seasonal Catalan food from the Garrotxa region. Combining the garden's tranquility with the ultra-modern glass design by RCR Arquitectes, the restaurant is a continuous extension of the hotel experience.
