Double rooms are for two people. The room has either two single beds, a double bed or a grand lit, i.e. a 140-180 cm wide bed designed for 2 persons. The latter is common in southern Europe, among other places. Additional beds do not have the same comfort as regular beds and can be a sofa bed. In some cases, the additional bed is part of the ordinary bed. Sometimes a single room can be a double room for solo use. "Family room" can be two rooms adjacent to each other.
The hotel rooms may vary; interior images should only be seen as typical examples.
