The pros:
The bed was good.
Location is stellar.
Joe was very quick to respond.
Check in and Check out were super easy.
The back patio is a perfect spot for breakfast.
Water pressure was adequate.
It is all one level with only a single step into the unit so it is relatively accessible.
Street parking is free (and competitive so that's a con, but that's probably normal anywhere in CA).
There are tons of restaurants nearby and it's an awesome place to visit.
It is very close to the airport (also noisy for the same reason).
Joe brought us extra bedding so we could use the couch and there were enough towels for the 4 of us.
The cons:
It is so small. The listing rates it for 4 people but it was tight and uncomfortable for 3 adults and 1 child. The couch is just a couch - no pull out bed. The couch is not comfortable for sitting or sleeping. Joe did bring an air mattress with air pump to us, which was very nice of him. We filled the air mattress to be ready for bed, then walked to the beach for a nighttime stroll. The air mattress was completely flat when we got back an hour later. The space would probably be fine for 2 adults and 2 kids of their own brood.
It is missing several typical conveniences: There was no broom (at a beach house), no toaster, no tea kettle, only 1 hanger in the closet, no shampoo or toiletries which had been advertised on the listing (there was hand soap), no garbage can outside of the bathroom and no extra garbage bags.
The bathroom is attached to the bedroom so if someone sleeping in the living room needs to use it at night, they'll need to come through the bedroom. (Maybe this is a pro for some groups.)
Neutral facts:
Some outlets only work with the light switch on.
The laundry is outside the unit and costs $1.50 per wash if I remember correctly. Bring your own detergent/softener.
There was only 1 set of keys to get into the unit which complicated things for us when our party wanted to explore different things. This may not be an issue for others.
The stove is electric.
Other notes:
I gave 3 Stars for cleanliness because the unit was very clean when we arrived, but we had no broom or cleaning implements so our stay in the unit did not feel clean after the first couple of hours. My hope is this will be remedied for future guests.
There was a Keurig in the unit but when we tried to use it we found it to be broken. We notified Joe that it was broken but it was not replaced before we checked out. We had brought our own French Press so we were able to survive.
I think this location is nearly unbeatable. We were a 10 minute walk to the beach, 20 minute drive to Sea World, 30 minute drive to San Diego Zoo and the airport.
Overall, I would stay here again if it was just me and my husband as the unit is a nice size for 2 people and it is accessible. I would just double check with the hosts that the coffee maker has been replaced and that a broom has been provided to the unit.
