I've just got back from a two weeks stay at Jeffs house.
The short version: Everthing was just perfect!
His house is as beautyful as shown on the pictures and is perfectly located to reach everything by foot or the free DART D-Link-bus.
Jeff is a wonderful, nice and careing host, who really does everything so you can feel comfy and at home.
If you come to Dallas you should really stay at this germ in Downtown Dallas
