Tucked within one of St. Petersburg's prestigious island neighborhoods, 135 Aranda St NE is a rare mid-century 1947 masterpiece infused with European flair and character. This home is an intimate retreat that stands apart from anything else on the market in Snell Isle. The main residence opens with a foyer and immediately goes into the living space with original oak hardwood floors and a striking decorative fireplace as the architectural centerpiece. The modern kitchen and dining capture pool views and flow seamlessly into the living areas to create the effortless indoor-outdoor connection. There are two bedrooms in the main home, each enjoy their own private en-suite bath, a layout for both full-time residents and guests. The differentiator is the rear casita. It is a fully self-contained guest suite with a private entrance, bedroom, full en-suite bath, dedicated mini-split and adjacent laundry room. Whether you're hosting extended family, welcoming long-term guests, or generating premium short-term rental income, these separate quarters deliver maximum flexibility while preserving complete privacy for all. Between the main home and casita lies your personal oasis, a tranquil pool and hot tub surrounded by lush tropical landscaping. A setting that feels far removed from the everyday yet is just moments from everything that downtown St Pete has to offer. This property has been thoughtfully maintained and upgraded, including a new solar hot water system, a refreshed air-conditioning system (2018), a fully updated electrical panel (2024) and a roof installed in 2016. Importantly, this residence sustained no damage or flooding from Hurricanes Helene or Milton, according to the owner, with this being a meaningful distinction in today's market. Beyond the property itself, the Snell Isle lifestyle is unmatched. Walk along Coffee Pot Bayou, play tennis or sand volleyball just near the water, ride your golf cart to festivals and world-class dining in downtown St. Pete, or catch a sunset at one of the sugar sand Gulf beaches just 20 minutes away. Two international airports are within easy reach. Also, opportunities to join clubs such as Vinoy, St. Petersburg Yacht Club, Women’s Club and St. Pete Country Club. Multiple private and public golf courses close by, too. Homes under a $1 million with a pool and spa and casita in Brightwaters neighborhood, a premium location, rarely become available. This is Snell Isle living at its most soulful.
