If you do a search here on HOTEL Riazor (even though the actual name contains Hostal) you should find the phone number and address as well. Ive stayed there a few times - as well as the Mercure. Pretty comparable in quality and price actually, but because of the locations, very different experiences. As of about 4 or 5 monbths ago, the pool on the roof of the Riazor was still closed...
