Here are hotel options across budgets and neighbourhoods in Singapore that are especially convenient for solo travellers because they’re close to MRT stations (easy, fast public transport), in walkable areas with lots of dining/entertainment, and generally feel safe and easy to navigate.

Luxury / Upper‑upscale

• Marina Bay Sands — Bayfront MRT (Circle/Downtown lines); direct underground connection, ~1–5 minute walk to the mall/hotel from the station. Great if you want iconic views, easy access to Marina Bay attractions and fast links across the city. (marinabaysands.com)

Business / Boutique

• The Fullerton Hotel Singapore — Raffles Place MRT (North‑South & East‑West interchange), about a 3–5 minute walk; excellent for solo travellers who want the CBD, riverside dining and museums within easy walking distance. (moovitapp.com)
• PARKROYAL COLLECTION Pickering — near Chinatown MRT (short walk); boutique, greenery‑filled hotel, very central for Clarke Quay/Chinatown and quick MRT access. (panpacific.com)
• Oasia Hotel Downtown — Tanjong Pagar MRT (about 2–5 minute walk); modern business hotel in the CBD with easy access to Tanjong Pagar dining and the Downtown Line. (oasiahotels.com)

Mid‑range / Budget‑friendly

• Village Hotel Bugis — Bugis MRT (3‑5 minute walk); in the Bugis/Haji Lane area — good mix of food, shopping and transport links (Downtown/East‑West connections). (villagehotels.asia)

Quick tips for solo travellers in Singapore

• Pick hotels near an MRT interchange (Dhoby Ghaut, City Hall, Raffles Place, Bugis) to minimize transfers.
• Carry an EZ‑Link / NETS FlashPay card or use the TransitLink app for faster fares; Grab (ride‑hail) is widely used for late/late‑night trips.
• Look for 24‑hour reception if you may arrive late.
• If you want to be in lively, social neighbourhoods: Clarke Quay/Boat Quay (riverside), Bugis/Haji Lane (cafés, shops), Chinatown (food + bars) are all very well connected.
• For solitude + convenience, choose hotels that advertise concierge/concierge desks and easy luggage storage — useful when you arrive early or have a late flight.

If you’d like, I can narrow this to: only budget hotels, only boutique hotels, hostels/capsule options for solo travellers, or give a shortlist based on a neighbourhood you prefer (Marina Bay, Orchard, Clarke Quay, Bugis, Chinatown).
