I worked as a visiting researcher at stanford university and I stayed at Jane´s place for more than 6 weeks. The house is right next to the caltrain track. Advantage: Menlo Park caltrain station is 3 minutes by feet. Disadvantage: You hear the trains every 15 minutes from about 5am until 11pm. Sometimes the rooms shakes! If you don´t sleep easily, it might be hard. The bedroom is ok, bathroom is shared. She was never bothered when I came home late because I worked until midnight often. Laundry is public and used from the neighbours too. Price is $2.
You can use the kitchen which is not always clean. She called herself "messy". I didn´t really care about that because I used to eat breakfast only.
Overnight guests are not allowed. My girlfriend visited me the last 2 nights and she was not allowed to stay there. It was not arranged before but there was no room for a discussion at her side. I tried to cancel the last 2 nights but she didn´t agreed over airbnb. After some days airbnb was very friendly and gave me some money back.
To sum up the place is ok if you work in stanford, palo alto or nearby. Airbnb top!
