Grace's place was just fine, but cold this time of year. It was the cheapest option I could find. The location is okay, it's walkable to a few things, but nothing is a less than 5-10 minutes, even to the nearest diner. Not convenient if you need to use CalTrain often or want to go quickly outside of Palo Alto.
It's easy to get in and out of the house and it's pretty clean. If you're traveling with a car, it's a good spot to stay, but room shares a wall with another room and does not have it's own bathroom. That being said, the bathroom was rarely in use and is kept very clean. Grace and her family are friendly and welcoming.
