• The Fortress Resort & Spa (Koggala) — Described as a luxury boutique resort with contemporary design and strong facilities close to Galle and the south-coast attractions. Good balance of boutique feel with resort amenities. (en.wikipedia.org)

Notes on choosing:

• Regions matter: pick Galle/Weligama/Tangalle for beaches and surfing; Bentota for classic west-coast beach/villa stays; Kandy/Nuwara Eliya for culture and tea-country; Knuckles/Sigiriya for nature and the Cultural Triangle.
• “Boutique” ranges from very small (5–20 rooms) intimate manor-houses to small luxury resorts (30–40 suites) — read recent reviews for service/style you prefer.
• Prices, availability and refurbishments can change seasonally; if you want I can check availability or current rates for specific dates and properties.
