I too have reservations at the Principe 11 for November. I followed some of the earlier threads here to see what other comments there were prior to booking. It generally received favorable reviews. ( only down comment being that the rooms seemed stark, but then I think they look contemporary according to their web-site - go figure
) Noelia in their reservations department has been most helpful in taking the time to answer some questions I had prior to booking. Will look forward to your comments after your stay there.
