Jeff's place is amazing. It's centrally located and close to everything you want to see in Hillcrest in a realistic walking distance. Jeff was very responsive. The place is clean and the beds & pillows are extremely comfortable. The place has all the essentials and although it's in an urban area I always felt safe. Make sure you checkout Jeff's area recommendations. Some of my all time delicious favorites in Hillcrest are:
Bread and Cie for breakfast and lunch
Parma Italian Restaurant (Amazing and best lasagna I have EVER had)
If you get out of Hillcrest, go to the Gaslamp District for dinner and go to my all time favorite Russian restaurant called Pushkin. Try the vodka flight and everything on the menu. Ask for Ike, he'll take care of you. You'll be in good hands.
