What this means is, you will be paying E33 ( $30, GBP 22) per person per night, assuming you share a room.

If I book a double room through
http://www.envergure.fr/campanileen.html,
I'd pay EUR 55,- per room per night, excluding breakfast.

With your deal, I would be paying EUR 66, - including breakfast for one,
(value of EUR 6,95). So that's more expensive rather then less expensive.

Or am I missing something?
