My partner, me and my 7 months old son had really a great time at Julian's and Nichole's place. They are really great hosts and provided us promptly with everything we might need for the long time we stayed over (+14days).
Also Bernal Heights is a great location to spend some quality family time right outside SF downtown.
We really felt comfortable and we can surely recommend their place as a great family friendly option for a stay over in SF.
