Hotel Grande Bretagne is the oldest and most famous hotel in Athens, Greece. Courtesy of Hotel Grande Bretagne Hotel Grande Bretagne, which opened in 1874, is the oldest and most famous hotel in Athens, Greece. The hotel survived both World Wars and was where the modern Green government was formed. Its rooftop restaurant, which has a perfect view of the Acropolis, was my favorite part. Tucked into the beating heart of Athens , with a perfect view of the Acropolis and mere steps from Greece's former royal palace, stands the Hotel Grande Bretagne . It's a noble name with a reputation to match, attracting powerful leaders and royals from all over the world, including British kings ( Charles III ) and American queens (Lady Gaga). Hotel Grande Bretagne, a Marriott property, is not only the oldest hotel in the city that birthed democracy, but it's also the most famous. So when I planned a trip to Greece , I knew I had to stay there. Could the 5-star hotel live up to its royal reputation?…
