I stayed in Carlos´ apartment for a month, and I am glad I picked this place for my vacation in San Diego. Carlos always replied fast, the check-in process was easy, the apartment was very clean, and it had everything I needed. It doesn't have a kitchen, but with the microwave, mini fridge and coffee machine I never felt the need for a kitchen. The bed was also super comfortable. The building is conveniently located right next to the I-805 in North Park, which made getting around San Diego fast and easy. You could barely hear any traffic noise inside the apartment, and I was almost always able to find parking right on the street outside the building. There's also a Vons (supermarket) within walking distance if you don't have a car.
I can definitely recommend Carlos´ place!
