Villa Pantheon was quite nice. Latin Quarter is a great location with both bus and Metro stops nearby, nice dining options, and nearby services including pharmacies, laundromats, and nail/hair salons.
There is no van or shuttle service available as advertised. The bathrooms are modern, and the breakfast is good -- coffee, teas, juices, fresh fruit, breads and jams, eggs and of course, pain au chocolat and croissants. They also serve the meats and cheeses and cereals and yogurt.
Service was good, but there were many new employees who did not seem familiar with the locale and the property.
