We've done trips to mission beach many times. This is one of the nicest places we've stayed. All rooms were as described. Things were clean, a few spots showing some wear and tear.
Best things about this particular house...
Lots of beach equipment. Chairs, toys, boogie boards, etc.
Perfect, quiet spot of the beach.
Big fridge/freezer, fire pit, outdoor shower, bbq access.
Our only issue was the parking garage. The gate codes were very temperamental and we couldn't get in touch with the management after hours even with following the instructions to do so.
