How to send your letter

  1. 1

    Decide who the letter is for

    Writing to the hotel itself — a complaint, a compliment, a billing question, or a lost-and-found claim — goes to Guest Relations. Writing to someone staying there goes to that guest, care of the hotel, and only works while they're checked in.

  2. 2

    Address it correctly

    For the hotel: first line Guest Relations, then COMO The Halkin, then 5-6 Halkin Street, then London SW1X 7DJ. For a guest: put the guest's full name on the first line, "c/o COMO The Halkin" on the next, the same street and city lines, and write their arrival date on the envelope so the front desk knows to hold it.

  3. 3

    Keep it to paper, and time it

    Send letters and printed documents — not cash or valuables. Mail for a guest should arrive during their stay, so post it a few days ahead; if you're not sure of the dates, call the hotel first. A hotel can't forward mail to a guest who has already checked out.

  4. 4

    Send it without a printer

    Write or upload your letter to PostPal with COMO The Halkin's address prefilled. We print it, add your return address, and mail it for you — no printer, envelope, stamps, or trip to the post office.
