I've stayed at a lot of Airbnbs, and John's place was exceptional. It was extremely clean and well maintained, he was super prompt to respond to messages, and even though the space was connected to his house, he gave plenty of privacy.
There were a lot of details that added to the experience like basic cooking ingredients, good lighting, quality bedding (that spelled so, so good), and keyless entry.
The location is on a quiet street within walking distance to Sunset Cliffs (perfect spot to catch the sunset). Like anywhere in SD, you need a car to get around, and luckily there is plenty of safe street parking.
I highly recommend a stay at John's place! I may even be back.
