The design of this hotel, not surprisingly, is modern, sleek, and quite nice. It is also fraying around the edges, however.
The hotel is a tram stop away from Gare Cornavin on the line toward the Palais des Nations, and therefore an easy connection from the airport. It is nestled between a main street (Rue Lausanne) and the train tracks in a nondescript location, but it is convenient.
The hotel's spa, sauna, and fitness center are terrific. Breakfast is not distinctive but certainly adequate. The wi-fi internet is free but can be a bit spotty. The staff is friendly and helpful.
The room itself was nice, though the "design" element here was just satisfactory. Not a problem, but not as precise or high-quality as the marketing materials or the public areas of the hotel might imply. And the bathroom facilities were fine, but rusting and wear around the fixtures suggest that the place could deteriorate quickly.
I've stayed at other locations in the area before, and did not find Design Hotel F6 to be remarkable, and it wasn't a great comparative value.
