Quick and Easy with a Good Price
We stayed only 3 nights and it was a very pleasant stay. Free Shuttle pick-up and drop-off included with perfect timing and no waiting. Breakfast included in the morning with waffles, cereal, pastries, orange juice, yogurt, coffee and more. Also there is a pool to swim in if the weather is warm enough. 
Also very close to bus service. #28, which goes to Old Town where you can get all connections you need. Or #84 which goes to Point Loma Cemetery and Cabrillo Monument and wonderful views from there.
The price was good and location is within 10-15 from airport but a little bit farther from downtown. 
We would definitely recommend it if you don't want to spend a lot.
