Catherine's place is totally wonderful. Being not far from the downtown (just a short uber/lyft ride away), the location is truly convenient to anywhere in the Bay Area. The flat itself is very comfy which makes u feel like home. The sweet neighbourhood has already got all you need, groceries, great coffee shops, nice restaurants with all kinds of cuisines.
Remember to check out the Bernal Heights Park nearby, which gives you the gorgeous view of the city.
