For decades, capsule hotels felt like a quirky souvenir of Japan: tiny pods stacked like train berths, just enough room to lie down, with shared bathrooms down the hall. They were the kind of travel story you'd bring home, not a format you expected to find at your local airport. That's changed. Capsule hotels have quietly spread across Europe, and they're becoming a normal budget option rather than a novelty.
London set the tone in 2025 when the Zedwell chain opened what's now the largest capsule hotel in the world, right in Piccadilly. With around a thousand pods and beds starting at about £30 a night, it undercuts traditional hotels in one of Europe's most expensive cities. One journalist who stayed there compared it to a no-frills airline: check-in happens at a tablet, a machine dispenses your key, and human interaction is almost nonexistent.
Spain has its own take. The Optimi Rooms chain runs locations in central Madrid and near Bilbao's bus station, with a sleek, futuristic look aimed at younger travelers. Its founders have said they deliberately built pods slightly larger than the Japanese originals, adjusting the format to local tastes rather than copying it wholesale.
The basic layout stays consistent everywhere: pods arranged in two tiers along long corridors, a curtain (sometimes electric) for privacy, a power outlet, adjustable lighting, and ventilation. Bigger luggage goes into lockers elsewhere, since there's no room for it inside. Guests keep their voices down, phones on silent, and many travelers actually find the setup more private than a traditional hostel dorm.
A newer offshoot is the airport capsule — unstaffed micro-rooms designed for a few hours of sleep between flights, ideal for early departures or long layovers. In Italy, several of these are run by ZZZleepandGo, which also operates a standalone capsule hotel in Milan, near Corso Buenos Aires and not far from Centrale station.
The driving force behind all of this is price. Solo travelers and business commuters increasingly want to spend less on a bed and more on the rest of the trip — and capsule hotels, once a Japanese curiosity, are now answering that demand across the continent.
