Here are well-suited hotels in Singapore for short executive stays, grouped by area with the key business-friendly reasons (location, quick transit, executive lounge / club, meeting facilities, or serviced-apartment option). I’ve indicated what makes each good for a short work trip and included price/availability notes where sources provide recent ranges.

Marina Bay / Downtown

• Marina Bay Sands — landmark property with extensive conference/expo space, easy access to Marina Bay business district and event venues; full F&B and concierge services make it easy for short, intense trips. (Good for head-office / conference trips.) (reuters.com)
• Mandarin Oriental, Singapore — strong corporate reputation, rooms with bay/city views, on-site meeting rooms and business services; central for Marina Bay offices. (luxurytraveltribe.com)
• The Fullerton Bay Hotel — boutique-luxury option on the bay with quick access to CBD and interchanges; good for short executive stays that value privacy and proximity to official/business districts. (luxurytraveltribe.com)

Orchard Road (best if you want shopping + easy MRT link to CBD)

• Conrad Singapore Orchard (and Hilton Singapore Orchard complex) — new/renovated large hotels on Orchard with executive rooms and private lounges, meeting rooms and easy access to Orchard Road retail plus Orchard MRT for quick CBD transfer. Executive rooms often include lounge access and business facilities. (seeingtheworldinsteps.com)
• Hilton Singapore Orchard — executive lounge and business facilities, convenient for short stays focused on meetings or quick client entertainment. (hilton.com)
• Pullman Singapore Orchard — modern business facilities, “club” / executive rooms and meeting space; positioned for digital-business travellers. (theluxuryeditor.com)

City Hall / Civic District (convenient for government / law / finance offices)

• Raffles Singapore — all-suite, historic property (premium option) for short executive stays when prestige and privacy matter; centrally located near City Hall. (luxurytraveltribe.com)
• Mandarin Orchard (Club Level) — Orchard/City Hall access, club lounge and executive benefits suitable for short corporate trips. (hotelsbeside.com)

Serviced-apartment / corporate-stay options (best if you want kitchenette, living area, or stays 3–14 nights)

• Ascott / Fraser / Oakwood properties (multiple locations: Marina Bay, Orchard, CBD) — serviced suites with kitchenettes, separate living areas, flexible short-stay options and corporate rates; handy when you need more space or self-catering on a short assignment. (expedia.com.sg)

Practical notes for choosing among them

• If your priority is fastest transit to Marina Bay/CBD meetings: choose Marina Bay Sands, Mandarin Oriental, or Fullerton Bay (Marina Bay). (reuters.com)
• If you want evening client entertainment + shopping: Orchard hotels (Conrad / Hilton / Pullman / Mandarin Orchard) put you on Orchard Road with many dining options and direct MRT links to the CBD. (seeingtheworldinsteps.com)
• If you need small meeting / boardroom facilities or an executive lounge for briefings: look for “Executive / Club” rooms (Hilton/Conrad/Mandarin Orchard/Pullman advertise these). Confirm lounge hours and included services when you book. (hilton.com)
• For flexible mid-length stays (3–14 nights) where a kitchenette or living room helps productivity, serviced apartments often cost-competitive vs. suites and include laundry/kitchen facilities. (theluxuryeditor.com)

Price/availability (brief)

• Business-friendly hotels in Marina Bay typically ranged recently from about S$296–S$743 per night on booking platforms (prices vary by season and lead time). For Orchard and CBD hotels, rates vary widely by property and whether you take a club/executive room — expect mid-to-high price bands for executive-level rooms. (Check dates for accurate rates before booking.) (expedia.com.sg)

Would you like:

• 3–5 options tailored to a specific district (Marina Bay / Orchard / Sentosa / Changi Airport area)?
• A short list filtered by approximate nightly budget, or only serviced-apartment options? If you tell me the district and a budget range (or travel dates), I can return live rate checks and direct booking links.
