We were 2 heterosexual males and based on a previous stay in the same building expected a double bed for the 1 and a sleeper couch for the other as we were overnighting for the Cape Town Cycle Tour. The couch we found was a bit small, for me to sleep on but I managed. I would recommend a sleeper couch to accommodate 2 people as in our case.
It would be fine for any other couple happy to share the 1 double bed.
