Very nice clean modern hotel with polite staff and high standards of cleanliness. Just needs to keep an eye on the queues in the bar - at one point 20 people queueing at 11pm with one member of staff on - so got bored and went to bed and drank the beer from the minibar instead. Unfirtunately no wine available. And at checkout at 10.30 10 people in the queue and one staff member on. Where is the management watching things like this?
