Great place and location! This is the perfect place if you're visiting San Diego. There's street parking on 6th Ave and Fir St. that is relatively easy to find. Just pay attention to the restrictions provided on the street signs.
This listing has a great view, a ton of natural lighting, and the space is ample. Just make sure you can carry your luggages/bags up stairs. In addition, this area is right under a airplane flight path. It means you will hear planes passing quite often.
It did not bother me but I also was busy in the city and back to this apartment in the evening.
Overall, this is a great choice if you're looking to stay central and within a walkable distance to other neighborhoods. The apartment is also quite secure.
One last note, there's a cute coffee shop, Mostra Cafe, a couple of blocks (4 minute walk) from this apartment that is perfect for those that want a coffee and pastry in the morning. It's within walking distance from this apartment. Perfect!
