We spend only two nights at Regina's place and everything was perfect. The neighborhood felt safe, location is very close to BART station and there are many coffeeshops, restaurants, etc. around. The free nighttime parking was good for us too. You get access codes to the complex and apartment itself, so no need for the usual key arrangements, which can cause problems and stress when you arrive.

Regina was very accommodating - she accepted a package on our behalf and was regularly checking how our trip is going. Pity we couldn't spend more time together, but our travel style is a bit rushed and we were very jetlagged - we wanted to see San Francisco in a day, so we didn't have much spare time left.
