Greg (the person who stays with irina) was a great accommodating host who have us a nice introduction to San Fran. The room was big and conveniently located near busy cafés and a short walk to the pier. He helped us lift our heavy luggage which was greatly appreciated since my friend broke her knee. If anything in his house for some reason didn't work, he promptly attended to it or compensated us for it. Highly recommended! :)
