I absolutely would recommend Robert and his cottage for a place to stay whilst visit Fort Worth. I stayed at his place because I was attending the Believers Conference at the Conference Centre in Down Town Fort Worth. It was very easy to get to by Uber and cost around $6-$8 each way.
I can't mention on what was within walking distance of the cottage as I never got the chance to explore, however the location is right off a main road, but the street it's self is very quiet and I felt extremely safe at all times, even coming home late.
Robert was very accommodating and even had stocked the fridge and cupboards with essentials and snacks which were a huge unexpected blessing.
Therefore, if you are looking for a place to stay I would definitely recommend Robert's.
