I stayed in Jenny's guest suite for close to four months while I did an internship. My stay at Jenny's place was wonderful. She is tremendously responsive and attentive to detail. If I needed anything during my stay, Jenny went out of her way to accommodate me. I am really grateful for her generous hosting.
The room I stayed in was partitioned off from the rest of my house, and the host respected my privacy. It has its own private entrance, shower, and living room, so it feels more like an apartment. There is no kitchen, but Jenny's place is close to a number of very good restaurants. While not super close to downtown Palo Alto, you can get there for about $10.00 with any ride sharing service. Even for longer stays, the lack of a kitchen wasn't a huge issue. The closest grocery store is a couple of miles away anyway, so Taqueria el Grullense will be your best friend for fast/cheap meals. There is a Starbucks near by if you need coffee, but Jenny provides a kettle if you prefer instant coffee. If you are staying more long term and like to excercise, I recommend the 24 Hour Fitness in Mountain View which is a couple miles away. Everything is spread out, so you'll get your fair share of walking / Uber rides in.
All in all, Jenny's place was exactly what I needed for my internship. I had everything I needed and more. I would highly recommend staying here if you have an internship which crosses standard subletting times, semester boundaries, etc., or if you just need a place to stay for a few nights.
