Yes Very much they are welcome.
Strange question, why wouldn't they be?
We as a couple (man and wife) can't speak highly enough of the City Star - great value for money friendly hotel
Absolutely couples are welcome, why wouldnt they be? Straight couples and same sex couples welcome - that was our experience
Sure, most guests when we visited were couples, what makes you think they would not be?
