Lina is a great host. She was very accommodating and responsive before the trip. We arrived somewhat late and were greeted by the entrance to the house. The house was nice, clean and as per description. She showed us around and explained the house rules.
The whole house is rented out for airbnb folks. If you want some privacy or expect it to be a quiet place it will mostly not going to happen. There is a curtain separating this particular sleeping area from the kitchen. While you can physically hide, you can't escape the noise. There were people eating, chatting and going in and out till around 11.30 ish or so.
Also, please make sure to read the description carefully. It states that it accommodates 2, and it has 2 twin beds for $48/night. Well, this price is for 1 person only, and there is additional $40 fee for the 2nd person. I know it is all listed and explained but I booked it using my cell phone and missed this tiny detail.
Overall, a great place to stay and enjoy SF bay area.
