Irina and her apartment are fantastic. Spacious, large studio and the balcony with the plants offers a great place to sit and relax during golden hour/sunset. Safe area, just don't go wandering towards Van Ness Ave on foot at night and you'll be fine...Hayes Valley is a very safe neighborhood with great places to eat. Irina is attentive and a great host and responds quickly when you need something. Hayes is easy to walk around, as is the surrounding neighborhoods of Lower Haight, and Japantown. Easy drive (~10 min) to places like North Beach and Russian Hill too. Would definitely recommend this cute apartment and Irina as a host for a stay in SF!
