My boyfriend and I stayed at Alex's place for three days. The house is nice and has 4 bedrooms, 2 bathrooms and a kitchen plus common space. Probably due to the fact that there are many people in the house, our bathroom was not super clean; anyway, it was ok, it had all the necessary and there were new towels every day. Also, Alex offers his guests many bottles of water, which are precious in the US since most of the time tap-water is not drinkable.
The house is located in the north-west part of San Francisco, not far from the Golden Gate Bridge; it is not very close to downtown but we used Uber and FordGoBike to visit SF and it was perfect!
Alex was a kind and careful host, gave us all the info we needed and the check in was super easy.
