Definitely go with the J.W. Stayed at both properties this year, actually at the J.W. last week, and it is far superior to the Westloop property.
Westloop still has the old foam mattresses while the J.W. has thick comfy ones. Turndown service also at J.W. complete with chocolates on the bed and spring water. Ask for a corner room. Entry hallway leading to room keeps all of the hall noise further away. Telephone in the bathroom and 2nd television. Hands down: J.W. on Westheimer.
Especially for $24 difference, J.W. is the way to go...
Hope you enjoy!
