I had a very comfortable stay at Ernest's place for 2 months this summer despite Covid, toxic air from Bay Area wildfires, and record heat. As the first guest in the unit after a family member had moved out, the kitchen, for example, was a bit under-equipped. However, Ernest's dad lives close by and brought over brand new cook and bakeware within 1-2 days and was, in general, very responsive to any issues that I or other guests in the building had.
Some general notes: the area is very residential and you'll need car to do anything (eg., getting groceries) although a bus line runs half a block away (didn't use). Parking in the neighborhood did not require a permit although the twice weekly street cleanings meant you had to be on constant reminder or else risk a ticket or getting towed. Cars doing donuts to mark up intersections with tire streaks is apparently a thing in SF so expect the occasional loud car or motorcycle. McLaren Park is a couple blocks away which offers some fantastic views / walks/ trails. As for the apartment itself, it had ultrafast internet, no TV, a full kitchen, and good daytime light from skylights – everything I needed for my working vacation. Bottom line is that it was a very cozy place (perfect for a couple or small family) and I will likely see if it is available again on my next visit.
