The Spa at Mandarin Oriental

Located in a former renaissance chapel, this spa has recently been voted best in Europe (Luxury Spa Finder) and is every bit as great as its reputation. Each second of your visit seems to aspire to be absolutely delightful and memorable: the genuinely warm welcome, the tranqulity of the place, even the excellent tea and fresh fruits while you wait for your treatment. Their two-hour treatments are all carefully tailor-made to your needs and might as well leave you purring contently. 
For the ultimate pampering session, try their signature “Oriental Harmony” treatment with two therapists working on you simultaneously. The incredibly synchronized ritual includes a warm scrub, head and foot massage as well as arguably the best body massage of your lifetime. (I actually expected to get dressed by butterflies afterwards.)
P.S. Mandarins Spa boutique also happens to be one of the very few places to sell the unique Mcely Bouquet cosmetics, developed and hand blended in a laboratory of the beautiful Chateau Mcely entirely from their local sources. An excellent souvenir or perhaps just a gentle reminder to pamper yourself more often.
