Our hosts did a great job in configuring the apartment - we really enjoyed the thoughtful touches such as having coffee and snacks available upon our arrival, and just generally everything was laid out really nicely.
The location is excellent - we carried the 3 supplied boogie boards to the beach each day in about 2-3 mins, and Mission Bay is just about on the doorstep. A coffee shop, two liquor/mini-markets and a couple of restaurants are within 200 feet. We were there during Fall break so there is a bit of noise around the area into the late evening, but I expect that's the case all over Mission Beach.
The parking space is definitely very tight - not out of line with anything else in the area - but anything bigger than a mid-size vehicle would be difficult, particularly if you plan to use it each day. We parked our mid-size and didn't get back into it until we were ready to leave, so it wasn't a major issue.
Overall the experience of staying at Krystle and Tal's was thoroughly enjoyable and we would highly recommend it
