ONE@Tokyo by insomnia

ONE@Tokyo by insomnia is a stylish three-star designer hotel overseen by architect Kengo Kuma, located near Oshiage Station. Reviewers consistently praise the stunning Tokyo Skytree views from the rooftop terrace and the generous 24-hour lobby lounge offering free pastries and drinks. However, guests frequently note the compact room sizes, exceptionally firm mattresses, and semi-transparent bathroom layouts.

Best for

• Solo travellers and young couples — The stylish, intimate atmosphere and the social 24-hour lobby lounge make it an ideal base for individual explorers and partners.
• Design enthusiasts — The hotel's unique architectural concept by Kengo Kuma artfully blends industrial concrete and metal with traditional Japanese wooden elements.
• Transit-focused travellers — Oshiage Station is just a short walk away, offering direct, transfer-free train connections to both Narita and Haneda airports.

Not ideal for

• Friends or colleagues sharing rooms — The open-plan bathrooms lack solid walls or doors, relying instead on frosted glass and fabric curtains, which limits privacy.
• Sensory sleepers — The mattresses and pillows are extremely firm, which may prove uncomfortable for those accustomed to softer beds.

Rating breakdown

• ALocation — Situated in a quiet, safe neighbourhood right by the Tokyo Skytree and Oshiage Station, offering excellent airport transit.
• BRooms — Impeccably clean and modern, though standard rooms are compact and feature very firm beds and semi-transparent bathrooms.
• A-Service — Staff are highly praised for their responsiveness, helpfulness with luggage, and fluent English, despite occasional late-night slowness.
• ADining — While there is no full restaurant, the free 24-hour lounge provides an excellent selection of fresh pastries, coffee, and drinks.
• B+Facilities — Features a spectacular rooftop viewing terrace and a cozy lobby, though the self-service laundry has only two machines.
• A-Value — Delivers far more than a typical three-star hotel thanks to its designer aesthetic, free round-the-clock lounge, and rooftop viewpoint.

Verdict

This hotel is highly recommended for solo travellers, couples, and design lovers who appreciate excellent transport links and free lounge perks. It is not suitable for those who require spacious rooms, soft mattresses, or complete bathroom privacy.
