Wonderland is in a great location... In addition to being walkable to the French Quarter and a great array of restaurants, music and art, its proximity to Crescent Park is a real asset. This park is beautiful; plus it houses a public dog run (full of nice pups and owners). The 2.5 flights of stairs you must climb to get across the Piety Bridge to enter the park are well worth it.
The Treehouse room had great natural light. The city sounds in the background are a bit different here - the crow of the rooster (not limited to sunrise), the horn of passing trains, the music of a piano being played, and the occasional drone of planes overhead. That said, I found I quickly adjusted as the bed is very comfortable!
