Will I really get a queen sized bed in my hotel room?

Larger chain hotels generally have larger rooms –  similar to what we experience in North America. Standard European hotel rooms are generally much smaller. The floor space around the bed may be large enough to walk around but space for luggage may limited.  The bed sizes are narrower.  Standard twin beds in Europe are 35” x 79” whereas in the US they are 38” x 75”. A double room may be two twins pushed together.

If the hotel website suggests they can provide either two twin beds or a queen it might mean they will push the two twin beds together.  If it is a concern and the website is unclear you should call to make sure you get what you want.
