hotel rooms question

Would you please help me phrase this correctly?

1) Room 101 is one end of the hallway and room 110 is the other end of the hallway. That's as close 2 room as we have. We don't have adjoining room.
2) The 2 rooms are not too far apart from one another.
3) The 2 room are close to one another. They are 3 room apart.
4) We have put two twin beds together to make a double so we can just as easily separate them to accommodate 2 people.

Thank you for your time
