Let's start off by saying that this unit is awesome! Avalon III has wonderful modern touches, a fully-equipped kitchen, and is centrally located to everything San Diego has to offer. The space is well thought out, very open, and spacious.
For 99% of people, this listing is perfect! With that being said, for anyone doing a relaxing staycation, you may have noise issues from the upstairs unit. My wife and I live in San Diego, so we only booked Avalon III as a staycation, opposed to an out-of-city or out-of-state visit. With this fact, we spent nearly all our time in the unit. Unfortunately, we had some very heavy-footed upstairs neighbors (they were probably part robot). Since the upstairs unit is not carpeted, the sound comes through the ceiling quite well.
Again, this unit is perfect for nearly everyone, especially if you're coming to San Diego to explore, and will be spending a majority of your time out-and-about. It's close to the airport, close to some of the best hidden gems in San Diego (like Izakaya Masa, Rubicon Deli, and Shakespeare Pub), is beautifully decorated, and has a fantastic view. Also, the beds are super comfortable! We highly recommend this AirBnb.
