Porter is a great host. The location is very close to downtown SD, and a lot of other cool places nearby. The space was clean and had all the amenities you'd need.
I will say that despite the great location, the free parking, and the amenities, the wifi connection was however very, very spotty. If you are planning on working from Porters Airbnb remotely, we definitely had poor wifi problems. I don't say this lightly or to deter you from staying at his amazing Airbnb, but it was a definite pain point for us.
Porter is however a great, responsive host, and did work to try to provide us with alternatives (which in all fairness didn't work any better).
