Overall, I would rate this as just an average vacation rental. The beach club, access to the pool and access to the beach are fantastic, but the condo itself was not great.
To begin with, the Del Mar Beach Club is a quiet spot, and the beach was great and pretty private/quiet as well. There are a lot of steps to get down the cliff, but you can see those in the pictures so that was fine. It's only about a 5 minute walk to the beach from the condo. The beach club is right by the Del Mar race track, and traffic was very congested due to an event there.
The pool is right outside the back door from the condo and again was never very busy. We enjoyed that.
Things we didn't like:
The check-in instructions we received from Homeaway were apparently not the instructions the manager expected us to get. A few phone calls upon arrival (she was very helpful) got us in, so it was only a mild irritation.
The condo itself smells very musty/damp. We opened windows and ran fans the whole time we were there and it helped a little, but not much. There were lots of little things that just show a lack of attention to detail throughout; I won't list them all but there were enough for us to notice. The wifi was a constant struggle; kept having to reset it to get signal and even then you wouldn't get it out in the living room, only back in the master bedroom where the router is located.
We've stayed at many Homeaway/VRBO places, and every other place there has been some sort of note/instruction out on a counter or table for you to help explain the rules and also welcome you to your vacation rental. In this case, we had to search through the drawers and found a stack of old papers and the instructions for check-out were somewhere in the middle of the stack of paper.
In the end, we enjoyed the location and access to the beach and pool, but the rest was average.
