I will attempt to be as balanced as possible in my review.
The Good:
San Diego is fantastic. The location in Hillcrest neighborhood is fantastic.
The description of the rental and the pictures match what you get. Read all the details though.
Kitchen is small but furnished sufficiently. Like most AirBnBs it has limited supplies, dull knives, dull can opener, etc but it does the job.
It has a driveway
The internet is very fast
The Bad:
You are only getting a portion of the downstairs of the house, you are not getting the whole house. Expect to hear the upstairs neighbors.
The hosts is very particular and upfront about only being available during business hours, recommends you keep keys locked at the house so you don't lose them, prohibits moving furniture to accommodate your stuff during your stay, etc.
The disappointing part of the stay was having to take time out of my vacation to go get a propane tank to use the amenities (BBQ pit, fire pit) advertised with the AirBnB. While host committed to reimbursing the cost of this it has yet to happen, it seems like I'll be getting stiffed. Of the many, many AirBnBs I've stayed at, this is the only host yet that hasn't figured out how to stock propane for their guest.
The age of the house and the furniture is showing. While the midcentury furniture looks good in pictures, it is not comfortable and, namely the dining room, is beginning to fall apart. I suggest you plan to sit carefully.
