Breakfast is ok, with not so many choices I would recommend it just for a short stay. WiFi is good, restrictions on VoIP are probably due to Qatar/Ooredoo, which is very unpleasant, and I've experienced better solutions in Qatar (e.g. in the Oryx Rotana it worked fine, and everything else is better too). Low and fluctuating warm water pressure need some patience, especially when showering. It can be pretty noisy - in my room it was due to loud prayers, probably from a close mosque.
