I had a great stay at Michelle's place. The room is very comfortable and has everything one needs. She even bought a toaster when I inquired about it. It is a very quiet and also sunny room and I slept very well there. It is true that the kitchen is not ideal for normal cooking and that was maybe the thing I missed the most. However, she makes it clear in advance, and you can cook basic things like pasta, rice, veggies, etc, so depending on what your needs are it won't be a problem for you.
Near the house (at a short distance walk) there are a couple of buses and not far you can also reach the Muni Metro and even the BART (30 minutes walk or 10 minutes by bus). The city center is reachable between 40 minutes and one hour, depending where you go. If you have a car, you'll make it in 20 minutes. Ubering home is not more than $10, so it is pretty convenient. The two flatmates are nice easy-going students and are not that often at home.
I would definitely recommend her place if you are not expecting a fancy place and you want a comfortable one not that far from the city center and for a quite ok price (for an expensive city like San Francisco).
Michelle is always ready to help and answered all my messages really fast.
I am very grateful for my experience there and would go back next time. Thank you, Michelle! It was an amazing month for me:)
