A& J's place is great. It's a well designed, nicely furnished and a well-located studio apartment that was perfect for a single traveller.
The space is on a hillside, behind the hosts' house. The backyard is nicely decorated with great outdoor seating options. The neighborhood is quiet and safe with adequate street parking. Dining options within walking distance are few and limited in variety. There's a grocery store about a mile away (Btw, a stroll down Isabel St. to the store is a great evening activity!)
The house is perfect for visitors to Los Angeles. It's freeway close to most of metropolitan Los Angeles but outside the hustle and bustle of DTLA, the Westside and Hollywood.
Evenings are quiet and the temperatures cool down. The studio is un-air conditioned which could be a problem if you are staying in on a hot day. I stayed during two 90 deg days and the provided fan was barely adequate in cooling the space during the day. But evenings are a definitely cooler.
The only other caveat is for those travelers with limited mobility. Being on a hill, there are a number of steps to negotiate.
