The Underground Spa & Wellness at The Logan Hotel

The Underground Spa & Wellness at The Logan Hotel is rated the number-one spa and wellness center in Philadelphia and has won Philadelphia Magazine's Best of Philly award for Best Spa to Visit with Besties. Guests rave about the warm, accommodating staff, fantastic massages — particularly the Alpine Arnica Deep Tissue Massage — and the overall luxurious atmosphere in this subterranean retreat. The spa features a heated saline pool, a relaxation room with candles and aromatherapy, and complimentary refreshments including fruits, cookies, tea, and coffee post-service. Reviewers describe it as a hidden gem with top-notch service, where therapists are highly skilled and tailor treatments to individual needs. Some guests note the pool area can feel crowded and is relatively small — best suited for dipping rather than swimming. Occasional organizational hiccups with couples' treatments have been mentioned, but the overwhelming consensus is that the massage services, staff professionalism, and serene ambiance make this a standout Philadelphia spa.
