We stayed in this loft for 7 days, and it was the great home base for visiting San Diego. We had no problems with the local area, and thoroughly enjoyed our stay.
It's certainly able to accommodate two people, though you have to be creative when trying to move around the space at the same time. I mistakenly booked for one person at first, and when I added my wife, we were charged extra when adding a second person. Just something to keep in mind for your booking.
The place was clean, and everything worked. We cooked in a lot. The fridge worked wel, though it may be useful to know the little freezer section at the top of the fridge is not quite able to keep frozen goods frozen for long (we tried). To be clear, the refrigerator works perfectly well for refrigeration.
The shower was fantastic. Great water pressure.
The WiFi is shared throughout the apartment building and does tend to slow down in the evenings. We were still able to watch Netflix on an iPad for the most part.
I saw another review mention noisy neighbors, but we did not have a single problem with noise in 7 days—and we stayed in most of the time! Perfectly cozy and quiet.
Kevin does a great job of setting clear expectations. You will know what to expect with everything ahead of time. I definitely recommend staying here.
