Lily has been a great host, very helpful, accommodating and generally nice. The house is very charming indeed, spacious and with a very nice shower. The kitchen is equipped enough to have a meal, although with so many restaurants around you might not want to eat at home so often.
The area is very convenient for transport. The BART takes you quickly to Embarcadero where you can connect with buses and the iconic Cable Car. There are also few buses that takes you to other parts of San Francisco. There are many homeless people around but although it may not look nice, they are harmless and they don't bother you.
