Elizabeth's place met our requirements of somewhere with good connections to dowtown San Fran and also SFO (airport). You can take the BART train form Macarthur station to powell/Embarcadero station for around $8.50 return and to SFO for $10.10.
The bed was very comfortable and there were plenty of linens and towels . I did not see much of the host or her daughter and dog but what I did see of them was a pleasant experience.
All in all it was a good stay.
