Love the apartment, the space & light are fantastic, the amenities are also amazing, and the staff is wonderful!

For the price, I was hoping to avoid a couple hiccups like appliance issues and unfortunately during the apartment staining, the crew was often loud in the morning/blasting music/smoking/peeing in bottles for several months. Additionally, the ropes keeping the pulleys up would get caught in high wind and bang against our windows like a loud drum. I don't blame the workers for trying... to have fun while trying to get their work done quickly & efficiently, but it was a significant and enduring pain.

Overall the place is great, & hopefully even better when the building finishes up some last touches.
