Elmer was a great host!!! He is very accommodating to what you have planned or not. His home is like a hotel. He has coffee and teas in the morning if you need. I have brought my little yorkie and Elmer and his lovable corgi London has made my dog very happy visiting.
Also, the location is great if you are using public transportation. Close by twins peak and golden gate park. Muni metro few exits to downtown.
