My girlfriend and I have been staying in long-term (1 month +) Airbnb's over the past year and we can truly say that this was one of our favorites so far!
Katie and Eric's place is perfectly situated atop Potrero Hill - you have a beautiful view of the city, it's quiet/peaceful during the day and at night, plenty of cute coffee shops and amazing restaurants to walk to nearby, and only a ~20 min walk to the Mission district, parks, or downtown. Their home was comfortable, clean, and exactly as advertised. Not only this, but they were some of the nicest hosts we've had the pleasure of staying with - extremely flexible, responsive, and even willing to help make an extension of our stay work!
I can't say anything but great things about this Airbnb. We were actually sad to leave and hope to come back one day. If you have any doubts about this spot, throw them away - it's the best!
