The JW has one giant plus, and that's its location. We literally walked a half-block to the Galleria, and the other areas around the hotel were safe and had lots to do. Everything else about the hotel was passable, but nothing to write home about. The lobby was small, with claustrophobically low ceilings, and not what you'd expect from an upscale brand like JW. The parking garage was confusing and a little on the shady side. The rooms were fine (ours actually did have a cute little window seat) but the bathrooms and dressing areas were tiny and had little counter space. On the whole, it was fine, but nothing more than adequate.
On a side note: there are great deals to be had on rooms at this hotel - we got ours for a song!More
