Earth Element Room – So Suites

So Suites; Earth Element rooms are grounded in simplicity, in tune with Mother nature. An enfolding haven adorned by Thai primeval wall paintings – mythical creatures. Entering the bathroom, a palatial sense of cool. Marble against blue, black and white tiles, full-length glass and murals reflected. A place to escape and contemplate. Inspired by caves found in North-Eastern Thailand.
