Karena's condo was a great base from which to enjoy Mission Beach. It is at the south end of the beach, away from the noise and crowds. But a pleasant stroll along the boardwalk (or better yet along the water) gets you to the restaurants, bars, amusement park, etc. My husband and I didn't have a car and didn't need one. Walking and an occasional lift or bus got us where we wanted to go.
The condo is lovely, with everything you need - comfy bed, well equipped kitchen and comfy couch. There isn't really an outside space, but you are less than a block from the beach, so that's not a problem. And the condo has beach towels, chairs and an umbrella so you can stake out your own beach front spot. We thoroughly enjoyed our days there. Very relaxing.
BTW...it you are looking for breakfast and don't want to go far, Beach Bowles just up Mission Blvd has great breakfast sandwiches. It took us a few days to discover that.
