Doris' lovely home is in a nice neighbourhood that is very close to supermarkets, pharmacies, cafes, and restaurants. It is also a 10-15 minute walk from the BART, which is very convenient for travelling both into the city and the airport. Although there are technically 4 sections of stairs leading to the apartment, I'd consider it to be two stories rather than four, so hauling luggage up was not much of a problem. Doris lives downstairs, and we were the only guests at the time, so we actually had the whole apartment to ourselves rather than just a private room, which was a nice surprise.
