Del's room is an amazing value, accompanied by a caring, attentive, and friendly host. Del provided a guidebook for restaurants to eat at and attractions to see, along with comfortable linens.
I prefer the cold, so this wasn't an issue for me, but the room did get chilly at night. Del does provide an extra blanket, however.
I also appreciated the visits by Charcoal, Del's friendly cat.
I highly, highly recommend staying with Del. If I make it back to SF, this will be the first listing I check.
