I stayed in 2 months in Davids apartment while working at UCSF. The unit was clean and has all you need. The neighbourhood is very beautiful, quiet, and safe. There are brilliant restaurants right around the corner and David provided a book full of all information you may need. It takes 10 minutes to walk to UCSF Mission Bay and 35-50 minutes to walk Downtown.
David is a nice guy and really helpful. The communication was always fast and precise.
I can really recommend staying in Davids apartment and I will miss life on Potrero hill.
