I had a lovely three night stay at Liliana's place, during which she made me feel very welcome and relaxed, and was also very helpful - including arranging for her husband to taxi me to the airport!
I hardly saw anyone else in the property during my stay, so it felt pretty much like my own place. It's in a pretty good location near to a trendy area on Polk Street (5 min walk) and close to the crookedest street in the world (10 min walk) and Fisherman's Wharf (15 min walk). There are steep stairs to get up to the flat, and many steep hills in the area - but I guess these are inevitable in San Francisco!
