Our stay with Tim and Chris was perfect! Their house is very nice in a quiet area. You can go easily to any point of interest of the city with the buses. They gave us a lot of great tips to enjoy the city. We loved Dolores St in Mission, especially Namu Gaji (Korean restaurant), bi-rite (fantastic ice creams), Tartine for the French pastries (as good as in France!). They also advised us to go to Ferry Building on Saturday morning where there was a market with restaurants booth. We also appreciated to go to a special event for Easter in Dolores Park, we won't have known about it without them! We enjoyed chatting with Tim and Chris in the evening and they help us to plan our trip in California.
Their dog Pepper is very sweet too :)
