Part of the renowned five-star St Pancras Renaissance Hotel, the St Pancras Spa is everything you’d expect from this gigantic name in luxury and hospitality. This subterranean sanctuary boasts Victorian features and incorporates elements of African, Indian and Far Eastern culture; you’ll pass through elegant brick archways before reaching the relaxation pool, steam room, sauna, gym and relaxation room, where you’ll be free to spend four hours luxuriating. Glide through the Victorian tiled pool, be massaged by the hydro loungers, meditate in the relaxation room, let the aromatic steam and sauna facilities cleanse you or get up to the state-of-the-art gym for a workout session. It’s up to you how you spend this time together, but there’s no more atmospheric place to unwind.
