Claridge House - Where Luxury Meets Restful Living In The Heart of Mayfair
Located in the heart of Mayfair, Claridge House by SLO, introduces a new chapter in London serviced living, redefining modern luxury through a philosophy of Slow Living. Set behind a heritage façade, this refi ned collection of luxury serviced apartments has been created for both short stays and extended visits, offering a calm, residential sanctuary that feels like a private home rather than a traditional hotel.
At the heart of SLO is the belief that time, presence and wellbeing are the ultimate luxuries. Every element of the guest experience is designed to encourage a more intentional pace, from discreet, design-led interiors to high-touch, personalised hosting. British craftsmanship, natural materials and a strong sense of place run throughout Claridge House by SLO, creating an atmosphere that is understated, restorative and deeply comfortable.
“SLO is a luxury hospitality concept centred on wellbeing and sustainability, backed by over a decade of Nestor’s hospitality experience and operational expertise. Every detail in our residences is chosen for purpose, longevity, and comfort. Hypnos’ commitment to British craftsmanship and sustainably sourced materials reflects the values that define SLO.”
- Fran Milsom, CEO, Nestor & SLO
Sleep is treated as a foundational guest need at SLO, particularly for guests staying weeks or months at a time. Rather than approaching sleep as a standard amenity, the brand has designed it as a holistic system, considering mattress performance alongside lighting, air quality, materials and calming rituals that support deep rest and recovery. This approach reflects SLO’s wider focus on wellbeing-led luxury, where comfort is carefully considered and quietly refined.
To deliver this experience, SLO selected the Eden Project Harmony Mattress by Hypnos, the brand’s most sustainable mattress. Handcrafted in the UK, the Eden Project Harmony Mattress is made using a considered blend of natural fibres, including Responsibly Sourced Wool, British wool, along with banana, orange, pineapple and cotton fibres. Naturally breathable, these materials help regulate temperature and support a comfortable, restorative sleep environment. Beyond materials, Hypnos’ low-impact delivery approach, including the use of electric and biofuel-powered vehicles, aligns with SLO’s operational sustainability goals. Designed with responsible end of life in mind, the mattress can be collected by Hypnos for recycling.
Sustainability at SLO is underpinned by a robust and measurable ESG framework that informs design decisions, operations and partner selection. Rather than positioning sustainability as a surface-level gesture, the brand focuses on long-term responsibility, from building retrofit and material choices to the partners it works with. Hypnos plays a key role within this approach, supporting both environmental responsibility and guest wellbeing.
“Sustainability in operations is about real numbers, not gestures. Hypnos’ responsibly sourced materials and considered approach to manufacturing and delivery help us reduce environmental impact in meaningful ways. At SLO, we define luxury through wellbeing and responsibility, and Hypnos enables us to deliver both at a consistently high standard.”
- Javier Llorente, Group Head of Operations and Guest Experience, Nestor & SLO
Claridge House by SLO is where guests can truly slow down and feel at home. Sleep is central to that experience, especially for longer stays, and Hypnos stood out for its craftsmanship, sustainability credentials and ability to deliver exceptional comfort.
Together, SLO and Hypnos represent a new vision for urban luxury hospitality, one that is calm, considered and quietly indulgent, where sustainability enhances the experience rather than limits it, and where sleeping well is an essential part of living well.
