Hotels For Trees

We’re proud to partner with Hotels for Trees to work together towards a more sustainable hotel industry and a greener planet by supporting global forestation projects.

Through this initiative, we’ll plant 1 new tree each time a guest chooses to skip their daily apartment clean.

We hope that with every tree that is planted, we can help make our planet a tiny bit greener.
