I overall had a great stay at Brett's place. Brett is a great owner and was very helpful and responsive. Check-in was also very easy.
The place is walking distance from downtown FW and although I came sometimes late at night, it seemed safe.
You probably won't find any better at this price in downtown Fort Worth.
Note however that the apartment is quite old (although very clean), especially the taps and the window frames which are rusty. Also, it is sometimes a bit noisy due to the close boulevard and the old windows.
Last, it is definitely missing a dining table - I had to have breakfast while standing up. For this reason, it is also quite difficult to cook as there's no space to prepare the items.
