Nice — here are solid hotel options in Singapore that put you close to major sights and easy public transit for independent sightseeing. I grouped picks by neighbourhood (fast access to the attractions you’re most likely to visit), and included the nearest MRT / why each is good for a solo traveler.

Quick tips before the list

• Aim for hotels near an MRT station (fast, cheap, reliable) — Singapore’s MRT connects most attractions.
• For solo travel look for 24/7 reception or good concierge, luggage storage, and easy access to food/transport at night.
• If you want cheaper stays with social vibes, choose a well-reviewed hostel or capsule hotel in Chinatown / Bugis / Little India.

Marina Bay / Esplanade (best for Gardens by the Bay, Marina Bay Sands, Merlion, Esplanade)

• Marina Bay Sands — iconic, directly above Bayfront MRT and a very short walk to Gardens by the Bay / ArtScience Museum; great if you want the SkyPark/view and immediate bayfront access. (marinabaysands.com)
• The Fullerton Hotel (and Fullerton Bay Hotel) — heritage/luxury in the Civic District, walking distance to Merlion Park and Raffles Place MRT for quick MRT connections. Good if you want classic Singapore city sights on foot. (fullertonhotels.com)
• The Ritz-Carlton, Millenia Singapore — Marina Bay luxury with easy access to the waterfront and museums; good location for solo visitors who want central comfort. (ritzcarlton.com)

Tanjong Pagar / CBD (great for food, cafés, quick access to downtown)

• Oasia Hotel Downtown — modern, greenery-covered high-rise near Tanjong Pagar / Maxwell; excellent for solo travellers who want a calm base in the CBD with short MRT walks to museums and the bay. (oasiahotels.com)

Bugis / Bras Basah / Little India (best for budget boutiques, temples, Haji Lane)

• Hotel G Singapore — centrally located near Rochor / Bras Basah / Bugis MRTs; reasonably priced, stylish mid-range option for exploring museums, Haji Lane, and Little India on foot or short MRT rides. (moovitapp.com)

Sentosa (if you want beaches / Universal / aquarium)

• Shangri‑La’s Rasa Sentosa Resort & Spa / Resorts World Sentosa hotels (Equarius, Hotel Michael, etc.) — stay here if you plan to spend time on Sentosa (beaches, Universal Studios, SEA Aquarium). Note Sentosa is separate from mainland MRT — many resorts provide shuttle access. (shangri-la.com)

Budget / Hostels / Capsule options (social, wallet-friendly)

• Hotel Bencoolen — budget hotel in the Bencoolen / Bras Basah area with easy walking access to Bugis / Bugis Junction and museums. Good practical choice if you want a private budget room. (bencoolen-street.hotelbencoolen.com)

• MET A Space Pod (Arab Street / Bugis) — capsule-style pods in the Bugis / Haji Lane area; compact, cheap, and very central for exploring Kampong Glam and Bugis. (metaspacepod.com.sg)

If you want, I can:

• Narrow these to a specific budget (luxury / mid / budget) and travel dates and check current rates/availability; or
• Map a 2–3 day solo sightseeing itinerary based on whichever hotel you pick (walking + MRT routes and timing).
