Stradey Park Hotel & Spa in Llanelli has gone on sale for £3.8m as the owners are looking to retire.
Gryphon Leisure is selling the freehold to the 77-bedroom property after 18 years of ownership. The hotel reception, main dining room and function rooms are located within the original manor house, which dates back to 1912 and was originally owned by local industrialist Alexander Raby.
Angela Saunders of Gryphon Leisure said: "We've loved every minute of our 18 years here. We had to reinvest heavily in the building when it was first bought and have continued to improve it, with the spa being one of the newest successful additions, and we're about to open a new rooftop restaurant, the 1912, within the next couple of months.
"We have benefited from staycationing, as customers have decided to holiday at home and not abroad in greater numbers, and that has given us some great success. Carmarthenshire has really developed as a holidaying destination in recent years, too."
Corrina Jones, business agent at Christie & Co, who is handling the sale, said: "Opportunities of this prominence, size and quality are few and far between within South Wales. Stradey Park Hotel & Spa offers the ideal platform for an experienced operator to move to South Wales or expand their current offering in the region with the acquisition of this quality asset.
"The business is being transferred as a going concern and we have been advised that there will be no disruption with regards to the day to day running of the hotel, accommodation, wedding or event bookings."
