Hospitality and lodgings Greek hospitality and lodgings Greek hospitality demanded the fair treatment of guests and the reciprocal treatment of hosts, outlined in the concept of xenia. Xenia demanded both abstract respect as well as the exchange of material goods, such as gifts and food. Much of The Odyssey deals with Odysseus' treatment by guests, and his own violations of xenia. Xenia also appears in other Greek myths, such as that of Baucis and Philemon, in which a disguised Zeus and Hermes are given shelter and food by an elderly couple after their neighbors refused to accommodate the deities; the couple is subsequently rewarded.

In addition to cities, trade groups or other organizations might appoint a proxenos to ensure their clients were treated fairly during visits. The office of proxenos was honorary, and came only with a title and the prestige associated with the appointment. Some scholarship suggests that although the proxenos was tasked with diplomacy, they also may have occasionally engaged in subterfuge or intelligence gathering in order to grant their native city the upper hand in conflicts.

These were organized around a central courtyard, and would have provided stables as well as beds.
