If you're visiting San Diego for all its attractions or just to relax, Colin's place is a wonderful private accommodation. It exceeded my our expectations! The studio was super clean with beautiful natural light and a very comfortable queen bed. Colin had a coffee pot for us, suggestions of things to do in San Diego, a fridge and clean towels. It was nice to spend our mornings out in the beautiful garden! Both Adams Avenue & North Park are a few blocks away from the house so it was easy to access its cafes, bars, restaurants, shops by foot. San Diego's public transportation in general is non-existent so prepare to Uber/Lift if you want to save time when visiting other attractions. But the house is 7 to 15 minutes away from everything which really made it an easy shot to the Airport, Downtown, Mission & Pacific beaches, Midway, and Balboa Park. Torry Pines Reserve & La Jolla Cove are a WORTH IT 25 minutes drive away from the city. So the house's location was EVERYTHING! There are buses but my partner and I had a limited amount of time and didn't feel like spending 40min -1 HR riding it although that was our original adventurous plan lol.
I also have to say that if you're vegan/vegetarian and happen to be in Downtown San Diego, I implore you to check out Cafe Gratitude. It will blow your taste buds off!
