Miles was a great host; easy to communicate with and flexible with our own schedule!
We LOVED the area of the apartment as it was within 5 minutes to SeaWorld and Ocean Beach. However, there were a few things that are important to consider.....
1) Although it is San Diego and temperatures are generally mild, this apartment is on the 2nd floor and it got quite warm (for SD) because there was no a/c. During the day and evening, it was almost always about 10 degrees warmer in the apartment than outside. We had to purchase a fan to help circulate some of the air. Miles did have 2 fans available, though, so that might work for you. We had a toddler and dog, so the lack of a/c might have been a bigger issue for us than it would be for others.
2) The noise level also wouldnt have been a problem if we weren't traveling with a toddler. Because the apartment was so warm, we had to leave all the windows open. Leaving the windows open meant hearing the "party" across the street, planes, and all the cars driving by.
3) Speaking of planes, they start flying over at 6:30am and dont finish until 11:30pm. They fly over all day, every day. In one hour long period we counted 12 flyovers. Again, this likely wouldnt have been an issue if we didn't have our son with us.

Despite those few things, we got through our vacation just fine.
Overall, the apartment is in a great location, safe, and is a steal for the money. Miles is a very easy going and a helpful host as well. This just might not be the place for you if you are traveling with small children.
