Room was well soundproofed - we were near the lifts but never heard them.
Breakfast had a good choice and constantly replenished.
Easy to get to from the airport by bus (only 1 change) with bus stop less than 5 minutes away.
Not sure I'd say 4 star though compared to other places we have stayed. Lacking in power sockets in the room for charging, not any by the bed without unplugging the beside light each side. No safe in the room, only at reception. Coffee sachets were 3in1 (coffee, milk & sugar), no option for without. Curtains didn't fit windows so if you like to sleep in a dark room, take an eyemask!
