Pros:
Economic
Friendly guests and open environment that invites communication
Nice host
Nice house
Bus stop literally right outside the house
Free to use the fridge and kitchen utensils
Floors, counters, etc. always clean
Close to downtown Dallas and various attractions
Cons:
Little privacy (since it's 5 beds in the living room)
Not the best neighborhood in Dallas (though the house itself is nice)
Shared bathroom with 5 people (doable, but you do have to time yourself to be considerate of others)
