Great — here are solo-friendly hotels in Singapore across budgets, with why each works well for one-person travellers (central location, safety, social spaces, easy transport, single-room value). I’ve picked reputable sources so you can check details and book.

Quick note on safety: Singapore ranks highly for solo travellers (very safe, English widely spoken), which makes walking, late-night food runs and using taxis/MRT straightforward. (timeout.com)

How to pick for a solo trip (quick tips)

• Location first: choose a hotel near an MRT station (Orchard, Marina Bay, Bugis, Chinatown, Little India) to save time and feel secure. (See individual hotel pages above for exact MRTs). (cntraveler.com)
• Want social/meet-people? Pick boutique lifestyle hotels (Hotel G, M Social) or capsule hostels with common areas (The Pod, Wink). (oyster.com)
• Prefer privacy and concierge help? Go luxury (Raffles, Marina Bay Sands, Capella). They’ll help with bookings, safety, and solo excursions. (cntraveller.com)
• Short layover or late arrival? YOTELAIR in Jewel is uniquely convenient. (en.wikipedia.org)

If you want, I can quickly narrow this to:

• a 3-hotel shortlist in a specific budget band (budget / mid / luxury), or
• hotels with the best single-room rates / best rooftop pools / best locations for nightlife or food.

(If you’d like that, tell me a budget range — otherwise the list above covers solo-friendly options across price points.)
