is there a separate bedroom? And is there a pullout couch in the main room?

That depends on the room type you choose. But, yes. This hotel has double rooms with a pullout couch in the main living area available.

Never seen that

The only rooms with separate bedrooms are the two bedroom loft rooms. Otherwise there are only studios.

Certain rooms have separate bedrooms, all rooms couches are pullouts.

Not a separate room, but their was a pullout couch
