The Telegraph "Two excellent restaurants serve a range of Italian and Mediterranean dishes, and there’s an in-house spa with a small indoor pool for use by all guests"
Oyster "Alternatively, the indulgent Orchids Hotel is a more attractive option in the same part of town for style-seeking travelers, but it doesn't have a pool, spa, or gym"
