Ivan and Wendy are great hosts, very nice and friendly. The communication with them was also very comfortable. The house is more than 100 years old, but it is very clean and neat inside. There is also a very lovely dog who is very quite. Also, the location is perfect, a lot of good restaurants within walking distance. I want to say thank you to Ivan and Wendy who made my first trip to San Francisco really impressive. This place is definitely on the top of my list next time I visit SF.
