Most of our rooms are what we call "Euro-Style." What the heck is that, anyway? Quite simply, it is a room that doesn't have its own bathroom ensuite, but rather, uses the shared bathrooms in the hall. Whoa there, don't panic. It's not like your junior-high locker room or anything like that. It's an individual, locking bathroom and you're the only one inside while you're using it. (Although I suppose you could invite a friend or two in, if you really wanted to. There's only seating for one, however.)
We clean them every day, so chances are pretty good they're cleaner than your bathroom back home. (Be honest now.)
Our ratio is more like 3:1, since we have four centrally located bathrooms with shower stalls, all on the 3rd floor where our twelve Euro rooms are. Consequently, it's pretty rare to see all four in use simultaneously, so there's almost always one open when you need it.
If you can think of a relatively succinct term that you like better than "Euro-style," please offer it up in comments, below. Until then, we'll keep listening to the Dutch and French folk snickering.
