We loved our stay with Ash and Ken and Paul the dog. The room is spacious with an ensuite bathroom. The bed was extremely comfy! The room has a fantastic view of downtown SF. Castro street is a little noisy, but that can't be helped so bring ear plugs if you're light sleepers. Ken made us delicious breakfasts and it was a pleasure to chat with him in the mornings. The house is just a short walk from the centre of the Castro district full of bars and restaurants and shops and the famous Harvey Milk camera store which now houses the Human rights campaign shop.
Close to the streetcar to get into downtown or you can take a walk to a rental bike place from where you can cycle to/over the GG bride.
