The Friday letter

One extraordinary stay, every Friday

A hand-picked place to sleep you probably didn't know existed: treehouses, rooms under the sea, glass igloos, cliff-edge cabins. Short, useful, free.

What you'll get

One verified extraordinary stay: why it is special, the room to ask for, typical prices and when to go.

Now and then, a short guide to a place with several unusual stays worth combining.

When to book, what to pack and the details hotel websites tend to leave out.
