Fair stay for what we pay
We stayed at the Travelodge for a conference at the Hilton. We choice it because it was amongst the lowest priced rooms within walking distance, and we weren't sure we would be staying more than one day for the conference. It turned out that we stayed in San Diego longer, so we completed our prepaid stay and moved on to the Grand Hyatt. I give this background to explain why as typically Hyatt quality travelers (or vacation rental/furnished rental travelers) we chose to book someplace obviously not on the same level as we're accustomed to. (I think it is really important when people write reviews to let the readers know where they 'come' from.
We did not have high expectations because of what we paid, and the hotel basically matched what we expected: It was in what some folks would call a 'sketchy' area, though I would say it was just off the beaten path and ethnic (and we had a fabulous breakfast at a nearby taquieria for a fraction of the cost of breakfast near or at the Hilton). We didn't feel unsafe in this area, but I'm guessing some folks may. 
The room was decent sized, typical of this type of hotel. It was reasonably clean, though like other noted, it was a bit worn (but again, for the price, what else could be expected?) and the beds were neither the worst or the best i've experienced. 
In general, I'd say that the hotel is fine for a night or two and for the prices they charge. The staff was friendly and they do offer free parking if you have a car (a plus), and free wifi (a plus). 
If you are expecting perfect, shiny new/shiny clean, fancy hot breakfast, Sealy plush top beds, in the heart of downtown, this isn't the place for you. If you are looking for a smile when you check in, clean sheets & hot water, free wifi and free parking, near the convention center for a bargain price and you aren't afraid to walk 10 - 15 minutes, this is a good option.
