This was our second stay at Francisco's, and again it was a great experience. Convenient, fairly quiet (unless you're a teenager and want to sleep till 10am), clean, and nicely equipped. I even did the 500-piece puzzle while I was there!
While we were visiting Palo Alto, someone broke into our rental car. The next morning I was using Francisco's dustbuster to clean out the broken glass, and a very nice neighbor came out and lent me his more powerful vacuum cleaner to finish up. So, friendly neighbors.
The construction is older, so you can hear other voices from neighboring units, so bring a sound machine. :)
