The room had a "private" bathroom - however it is on the other side of the breakfast room, so if you want a shower in the morning you end up walking through the breakfast room, complete with guests, wearing just a towel and an attempt at a nonchalant smile!.
Also the room, though OK, is not a patch on the photo.
Also, when yo get there you find it is not "Zero room and breakfast" at all but "White B&B"!!! This makes it almost impossible to find and there is NO SIGN for it outside the building.
The area is somewhat run down (though only 10 minutes walk from the much nicer historic centre). And so that you can judge the area it is right by the tram and railway stations and we saw several ladies of "Negotiable virtue" nearby.
That said the room itself is fine apart from the shower and loo being on the other side of the breakfast room, and the staff are friendly. It was clean, and kept clean.
