Somerset House occupies 10 Florence Road in Southsea, a coastal neighbourhood south of Portsmouth city centre. Run by The Mercer Collection, it operates as a hotel serving visitors to the seafront area. The property sits within walking distance of Southsea’s promenade, pier and beach attractions, making it a practical base for exploring the town’s Victorian seaside character and museums.
Florence Road itself lies in a residential quarter of Southsea, with easy access to local shops, cafes and the Solent waterfront. The postal district PO5 2NE places the house in the heart of the holiday accommodation zone that has developed along this stretch of the coast. Guests can reach major attractions including Southsea Castle, the D-Day Story museum and the seafront gardens within minutes on foot or a short bus ride.
