I had a wonderful time at Erika's place.
The room is really comfortable with a very good bed an plenty of space. A really ample closet and lots of drawers. Location is excellent, with a BART station nearby, it is really easy to arrive there from SFO airport and also very convenient for your trips to the city. I rented a car for a few days and there was no problem at all parking it for free in the street behind Erika's home.
Obie (Erika's dog) is very shy, might bark, but never be aggressive. I managed to befriend him and was a nice company.
Erika is an excellent host, very thoughtful and with lots of suggestions for my visits around. She definitely was key in such a pleasant stay.
