Serhan was a great host! He rents 3 rooms at once, so you might encounter other Airbnb renters during your stay. But once Serhan agrees to host you, you will be given a passcode for his front door and an additional passcode for your personal room once you get in, so you don't have to worry about your privacy with other Airbnb renters.
My friend and I rented the Pisa Room which had a queen size bed, flat screen TV with access to Netflix, and a closet. The only thing missing during our visit was a trash can. My friend researched the house somehow and found out that one of the rooms has a personal bathroom while we and our neighbors shared the downstairs bathroom. Serhan also provides soap and shampoo, so you don't have to necessarily pack those toiletries. There is a sign indicating no toilet paper should be flushed down the toilet and should be thrown in the trash, but that wasn't bothersome. There is a mini fridge and a microwave on the second floor if you have any groceries and leftovers. The place was heated but our room was slightly cooler than the hallway, so I'd suggest bringing a sweatshirt if you're sensitive to cool air.
The place is a half mile away from the Painted Ladies but the location also has plenty of nightlife, restaurants, cafes, and stores. If you're here to tour San Francisco, I'd highly recommend Serhan!
