This depends on the property and the landlord. Landlords can choose whether to accept couples or not.
This information is shown in the "House Rules" section of the listing.
However, if you only want to see rooms and properties that allow couples, there is a filter for "couples" on our search page.
One more thing: some landlords will charge extra for couples in properties/rooms to cover the extra usage of water/electricity etc. Check the Landlord's Policies in case any of these extra costs apply.
