First off, location. I do want to clear the air for anyone concerned or finding themself in a similar situation. I arrived at about midnight due to some flight days. Having known nothing about Mission Beach and arriving at night, staying off a main road was a little bit concerning at first. For anyone else in a similar situation, do NOT be concerned. You'll see its a very safe tourist/travel destination. Once you walk 100ft to the beach bike path or bay bike path, and walk a few blocks, you quickly see how safe it is. Families have their sliding glass windows fully open not even 10 feet from the paths - check out zillow if you are curious - these places are really nice/not cheap. There is nothing to worry about in my opinion. Further, the location is incredible. You really can find plenty of entertainment all across Mission/Pacific Beach without ever leaving. You have the Bay for the calm waters and you have the Beach for the surf. Biker/walker friendly paths everywhere too. You really don't need a car and I honestly think you end up seeing more and getting a better feel for an area walking or on a bike.
Secondly, the amenities. You can't beat this. Patty was so great and inviting and insistent on showing me all the fun toys that they have. There are bikes with locks, SUPs, kayaks, beach chairs, umbrellas, toys, and surfboards. I ended up buying a surfboard to avoid the costs before going south to Baja after my conference, but until someone came through, I was able to use one of her loaners. FYI, for surfers, the beach works for sure, but when my wife came, we ended up going to Blacks - there's a lot of good spots in SD; if you are visiting and an avid surfers, get a car, its worth it. For me though, I was going to work during the day so the bike was perfect to do the path and find a little spot to myself or join the crowd at the better break more towards pacific beach (5-10 min bike).
Lastly, the place. The place was very cozy and nicely decorated. The white painted wood panel walls in comfortable clean place reminded me of a surf shack I lived in at a point. She even left a bag of coffee for me to get through the. There is a toaster, full fridge, cookware, dishes, utensils, and oven so you really don't need to eat out at all. There is also a grocery store about 1 mile away, which is a quick ride. One of the bikes has a basket in the front to.
All in all, a great trip and wish I could spend more time there. Thanks so much to Patty! She was great and responsive.
