Rooms can be cold in winter time, having no heating, only aircon. However, possible to ask for a separate heater to be placed in the room.
Also, the pool is cold in winter time.
Slow service in hotel restaurants, with a few individual exceptions (some people do a great job, while some of their colleagues are oblivious, as every where else, right?)
The hotel security team is fantastic, providing extraordinary assistance when requested. They really know what service minded and customer focus means!
