I had a great stay at Carina's. She and her family (including the dog) made me feel very welcome indeed.
The room is large, bright and very comfortable. Having your own entrance is a real plus if you leave early in the morning and come back late at night.
It is an easy walk to Stanford, but having access to a bike made a real difference. It really is the best way to get around Palo Alto.
Having said that, Carina's house is very well located near all amenities, restaurants and bar. You can easily walk anywhere.
In a word, a great stay and a great host! Thank you!
