For starters, the apartment and furniture is older than it looks in the photos. Many things were just sticky - hard to open, hard to close, etc, and the apartment is clearly older than it looks in the photos. Everything is generally usable but it was older/less well-maintained.
The real issue for us was dealing with Todd. The water heater broke around day 2 of the 7-day visit, meaning we had no hot water and could not take a shower. Long story short: Todd told us he would be unable to fix the water heater for several days and offered us a $200 partial refund (about 12% off) or, if we wanted to move out, would refund us the days that we were gone. The problem was this was Labor Day weekend, and we could not easily find a new place without paying 2-3x the cost. We explained our situation to Todd and told him that because he offered to refund us the cost for the days we weren't there if we moved out, whether he'd be willing to offer a bigger refund, as we thought $200 off to have no hot water for 4 days was way too low. We thought our request was reasonable. Instead, Todd said the best he could do was $250, and after much back and forth, would not budge on the number, admitted that having no hot water made the place uninhabitable, and said we should just move out. This escalated a very difficult situation for us and we ended up having to seek a resolution through Airbnb. Not only did we have no hot water for 4 days, but we had to deal with a very difficult host and look at possible alternative housing when we should have been enjoying our time in San Diego. This was one of the worst experiences I've ever had with an Airbnb.
Our experience might be idiosyncratic, and if everything goes well in the apartment then this might not be an issue, but it was a nightmare for us. Had we known any of this would happen, we never would have booked Todd's place.
