Our stay with Chris and Tim was very nice. The room was clean, the bed slept very well and in the morning we woke up with a nice cup of coffee and breakfast with a fruit salad and self-made jam. The location of the house is somewhat out of the city center, but if you follow the directions and suggestions for busses that Tim and Chris provide it is very easy to get around. Also ask them about suggestions for restaurants and ice cream places, we went to some places they suggested and the food and ice was very good! If I stay in SF again I would definitelty stay at this place again.
