English is widely spoken in Europe so most of the time communication is no problem. Pick up a phrase book at your local book store. You'll find it neatly rolled up or folded up on the top of your bed when you arrive at the hotel. Unfold or unroll the feather bed and sleep under it. If you find you are too warm, you can ask the hotel for a regular blanket.
Pillows stuffed with feathers are the norm in the region.
You can't move the beds apart as their frames are attached to the wall. While the beds may be closer than you wish, each person can toss and turn without disturbing the other. The windows in your hotel room will swing wide when you turn the handle in one direction. If you have a balcony door, you'll usually find the same tilt system. Most hotels in the region do not supply wash cloths.
