It was a beautiful place - a stucco white design with large open windows, so you could look out at the beach while you were eating.

Does it mean the windows were all open?

Windows can only be obstructed if something is placed in front of the window which prevents you looking/seeing through it, such as a drawn curtain.

If there is an something the other side of the window, then it obstructs the view not the window, since it is still possible to see through the window to the obstruction.
I'd add a further interpretation - I'd think of these as windows with large panes of glass, giving a good view, rather than windows with lots of framework and small panes of glass that obstruct the view rather.
