Visited BT Siena in September 2013.  Due to construction delays, the planned completion will be around December 2013, but I expect the entire work to be completed around June 2014, although the project team promises to deliver before that (nothing new!)  Due to heavy rains that week, I could not go into places I would have wanted to see.  Some of the apartments have been completed, and when I went up to my apartment floor, the lake view and the sea view were magnificent.  One of the main reason to by at BT Siena would be the lake and sea view with a very high probability that the view will not be blocked by another high rise due to proximity to water logged areas.
