I would guess NO. Our bathroom didn't even have a wall or a door...just glass separating it from the bed! Very dim lighting; but no privacy! With no window, it felt very confining.
The more expensive room does have a bath but email hotel to check which ones
My brother and his wife were upgraded to a room on 5th floor (I think) that had a bathtub. It might be the only room in the hotel that has a bath. This was about 2 years ago. Why don't you contact the hotel directly and ask. I've always found them very friendly and stay there often
its not necessary to put a bathub on this rooms, considering the price which is too low.. being without a window s a plus points of this hotel which they considered the location and the guests privacy...
No, it does not.
