Marga was very friendly and helpful, she even picked us up from the train station and gave us a quick tour of the city. We were made very welcome in her home, and her family were all very friendly. The location is good, about 15 minutes walk from the old town. The walk back uphill is a great way to burn off some of the amazing pinxtos you'll eat for dinner, but isn't too strenuous.
The room is great, Marga gave us a nice bottle of Rioja as a welcome gift, and you have a private bathroom.
