This apartment (actually a set of them) is a great location in the Gaslamp Quarter. The bedroom in unit 21 where I stayed overlooked Fifth Ave, and there was a futon in the living area that could have slept additional guests. I liked having the fully stocked kitchen with utensils/dishes, a fridge, stove top, sink and coffee maker. The coffee maker even went on the fritz during our stay and a new one came soon after I made the host aware. Wifi worked fine, and I liked having a keypad instead of a key to keep track of.
The only drawback to this apartment is that it's on a very lively street with a lot of noise at night. The host kindly left earplugs, and this noise level was noted by prior reviews. Still, what I didn't think of was that I wouldn't hear things I wanted to like alarms (for wake-up, and accidental fire alarm set-offs). The walls are also quite thin, so I could hear activity in the other 3 apartments on the hall, two of which seemed pretty rowdy groups.
