I highly recommend Quang's AirBiB. It is in a great location to get to everything. It felt like your own quiet home with a backyard area to relax if you so choose.
They have great furniture and a big kitchen for cooking. The bed was the best bed I've slept in at an AirBnB. Quang was supper responsive and when we had a small hiccup, he was proactive about resolving it.
Will definitely be using his AirBnB during my future stays in Dallas.
