Zack was a very gracious host! Check-in was smooth and easy, and he checked up on me while I was staying at his place. The place is a secure house (you will receive a four-digit key code for the gated door) with a shared living room, kitchen, mini dining room, and shower/bathroom. There are security cameras in the kitchen and entrance up the stairs to the house. There are three (3) bedrooms. A private bedroom with two (2) beds and a key code lock, a bedroom with two (2) bunk beds - four (4) beds in total, and my bedroom with two (2) beds. If you want privacy, you'll want to request the key code bedroom. The other ones do NOT have a lock - they're always unlocked. Zack's place is about a 10-min walk from the Colma BART Station. It's a 30-40 min ride into the city. It's a 20 min ride to the SFO airport. Both trips aren't that bad. The kitchen is fully stocked with a stove, fridge, and microwave.
