Willem and Katie's place is your top pick when visting TCU!
It is in very close proximity (was able to take the bike every day) to the university area and also offers some amneties like nearby restaurants or groceries.
Also, the ride to downtown is not that long and an uber should get you to the stockyards or other cool parts of the town for less than $10-15 (and there is plenty to explore).
Overall, the master bedroom was very nice and it offered a place to retreat and refresh - offering a private bathroom /w shower and a walk-in closet is a nice extra. Everything was clean and nicely arranged on my arrival.
Also, the hosts are very lovely and responsive. Most of the time, their son, Stephan, was on site and very kind and helpful.
Overall, a nice place to stay when in FW!
