Is this sentence OK? I would like to integrate two ideas into a sentence. One is that international students are guaranteed on-campus accommodation, while the other is that the type of rooms for them is a 3- or 4-bedroom. I put it this way: International students are guaranteed on-campus accommodation that is a 3- or 4-bedroom. Does it correctly interpret what I'm trying to say? Or there is a better way to put it? Your suggestions would be greatly appreciated.
