Don't know what your design style is, but I would want to modernize the exterior and emphasize the clean lines. I would paint it all a light gray or white color and use white or gray for the larger trim. Replace the ornate railings with plain glass and stainless steel. Remove the bars from the windows, the decorative corbels and perhaps replace the windows with something simpler and more modern. Remove the pergolas over the balconies and use some colorful modern canvas awnings. Remove all potted plants and extraneous ornamentation. Replace hanging sconce on balcony with recessed lights.
