Great — here are centrally located hotels in Singapore that are especially good for solo travellers, across budgets and neighbourhoods. I’ve noted the area, nearest MRT, why each works for someone travelling alone, and given a source so you can check details and current rates.

• Hilton Singapore Orchard — Orchard Road (Somerset/Orchard MRT). Large, safe hotel in the shopping district with easy walking access to cafes, malls and the Botanic Gardens — good if you like convenience and a busy urban base. (hilton.com)

• Marina Bay Sands — Marina Bay (Bayfront MRT). Iconic, central luxury with direct MRT access and lots of on-site dining/entertainment — great if you want a one-stop luxury hub and easy evening activities. (marinabaysands.com)

• The Fullerton Hotel Singapore — Marina Bay / CBD (Raffles Place MRT). Heritage luxury on the waterfront; excellent location for museums, riverside walks and safe late-night returns. (fullertonhotels.com)

• Oasia Hotel Downtown — Tanjong Pagar / CBD (Tanjong Pagar MRT). Stylish, greener skyscraper in the business district; quieter, modern facilities and very close to Tanjong Pagar’s bars/restaurants. Good for solo travellers who want a calm base with quick transport links. (oasiahotels.com)

• PARKROYAL Collection Pickering (on Pickering) — Chinatown / Clarke Quay (Chinatown/Clarke Quay MRT). “Hotel-in-a-garden” with sky-gardens and short walks to Chinatown and the riverside nightlife — handy for food/heritage exploration. (oyster.com)

• Hotel G Singapore — Bugis/City Hall area (Bencoolen/Dhoby Ghaut/Bugis MRT). Mid‑range, design-forward, centrally placed between Bugis and Orchard — budget-friendly, social, and excellent for walking to museums/food spots. (oyster.com)

• The Clan Hotel — Telok Ayer / Chinatown (Telok Ayer / Raffles Place MRT). Boutique luxury with strong local character; ideal if you want a stylish, central base near top restaurants and heritage walks. (theclanhotel.com.sg)

• ibis Singapore on Bencoolen — Bencoolen / Bugis area (Rochor/Bencoolen/Bugis MRT). Reliable budget chain in the cultural/shopping district; simple, safe and very central — great value for solo travellers. (ibissingaporebencoolen.com)

• The Pod / MET A Space Pod (capsule hotels) — Kampong Glam / Bugis (Nicoll Highway / Bugis / Arab Street areas). If you’re solo and on a tight budget but want privacy and a social hostel vibe, capsule hotels are centrally located and very popular with solo travellers. (thepodcapsulehotel.com)

Quick tips for choosing:

• Pick a hotel within a 5–10 minute walk of an MRT station — it makes solo navigation and returning late much easier.
• For socialising, choose boutique hotels with bars/lounges or a centrally located capsule/hostel. For peace and safety, larger chain hotels in Orchard/CBD are excellent.
• Always check recent guest reviews (last 3 months) for staff helpfulness and neighbourhood vibe before booking.

If you want, tell me your budget (per night) and preferred neighbourhood (Orchard, Marina Bay/CBD, Bugis/Arab Street, Chinatown/Clarke Quay) and I’ll shortlist 3–4 options with approximate nightly ranges and direct booking links.
