We had a great stay at Bassel's nice apartment. It is well located to explore the city via Muni, good shops and restaurants nearby. There are three minor cons:
1. No free parking in the week for more than 2 hours (you will have to walk 5-10 minutes for free parking)
2. There is no kitchen sink and therefore all cutlery, cups, plates etc. are one-time use plastic and paper only.
3. You here noises from the apartment above where Vassel is living. At night it was completely silent, but in the morning and during the day you here every step from above.
I also think that the apartment is a bit too pricey - but that's San Francisco. So I still give full 5 stars - the apartment is great and Bassel a very nice host.
