We’re Opening a Private Spa!

Since Winter 2018, we began to realise our dream of offering a private spa for the sole enjoyment of our hotel guests. Expected to open in fall of 2019, it will feature a custom Finnish sauna, rain-fall walk-in shower, lounge, and massage room. While staying with us, guests may reserve one-hour sessions for their private enjoyment. No need to share…with anybody.

If you want to be the first to know when it opens (and take advantage of the exclusive opening week) leave your e-mail address here.
