Yotel, the British hotel chain that models its small accommodations after airplane cabins, is planning to open a hotel in Boston within the next few years.

If the company completes its plan, guests would check in at automated kiosks and possibly store their luggage with a robot concierge. Inside the rooms, most of which are 170 square feet, beds turn into sofas and slide part way into walls to create more space during the day.

In other locations, some rooms are equipped with bunk beds.

The Boston hotel would be another step in the company’s plan to expand around the world in the next five years.

Currently, there are three Yotels in airport terminals — at London’s Gatwick and Heathrow airports and at Schiphol in Amsterdam — and a 669-room facility in New York that opened last June. Rates in New York range from $179 to $399 for a standard room.
