It was our first time using air bnb so we were a little skeptical but Lina and Alex were great. They were on vacation themselves so they routed us to their daughter Helen who was just as great. Always available and answered all of our questions.
The place was very nice. It was also very clean, which is something I value. The unit was modern and spacious enough for 4 people. It was near the bart stations, as well as the muni. An über ride was jus about 20 mins away from union square.
I definitely recommend this place to anyone and any other place Alex and Lina host.
