William’s place was just as described and my family and I really enjoyed staying there. We were very close to the attractions in Balboa Park which is where we mainly wanted to visit but were also close to Little Italy and the bars and restaurants there.
Street parking was pretty easy to find but my family and I visited on a Monday and Tuesday, so maybe the situation is different on weekends.
William was very responsive with questions I had ahead of time and provided helpful recommendations of places to visit in a folder he left us on the kitchen counter. Check in was nice and easy and check-out was the same. Would recommend staying at his Airbnb.
