Overview

It doesn't get better than this ... sweeping gulf and beach views, the soothing sound of waves, and instant relaxation at The Castillian on Longboat Key. Residences here rarely become available, so all that's left to do is embrace the casual laid-back lifestyle. The condo's centerpiece is a beautifully renovated open kitchen featuring solid wood cabinetry, granite countertops, GE Monogram appliances, a large stainless steel sink, and a stylish built-in desk area. Both bathrooms have also been updated. The owner's suite, guest bedroom, and great room all open to the balcony, which is equipped with a hurricane shutter for added peace of mind. The Castillian consists of two 30-residence buildings and offers assigned under-building parking, a private storage closet, a heated pool and spa, an outdoor grilling area, and a tennis/pickleball court. This pet-friendly community is conveniently located near Publix and just minutes from the restaurants and shops of St. Armands Circle.
