Great — here’s a curated list of Singapore hotels known to offer rooms or suites with private balconies/terraces and a romantic ambience, organized by neighborhood and price tier. I’ve included which room types typically have outdoor space and why each is romantic. (I’ve cited official pages or reliable sources for the balcony/terrace features.)

Luxury / Splurge

• Capella Singapore (Sentosa) — villas & premier sea/garden rooms with terraces, many villas have private plunge pools or outdoor terraces (e.g., Constellation / Palawan villas). Romantic because of private garden/sea-front setting on Sentosa, private dining options and secluded pools. (asmallworld.com)

• The Barracks Hotel Sentosa (Sentosa) — heritage luxury hotel whose Premier rooms (upper floor) have private balconies and ground-floor suites/garden suites have patios or pool access (some with semi‑private jacuzzi). Romantic for its intimate colonial‑style setting, secluded pool and historic ambiance. (thebarrackshotel.com.sg)

• The Fullerton Bay Hotel (Marina Bay) — waterfront suites frequently advertised with private balconies overlooking the Singapore River / Marina Bay — ideal for sunset views and fireworks nights. Romantic for sweeping bay/city skyline views and upscale rooftop/restaurant options. (tripadvisor.com.sg)

Upscale / Romantic city‑views

• Mandarin Oriental, Singapore (Marina Bay) — several suites (e.g., Marina Bay Suite, Sea View Suite) explicitly list a private balcony with Marina Bay or sea views. Romantic for panoramic bay views, luxurious in‑suite services and the Marina Bay waterfront setting. (mandarinoriental.com)

• The Fullerton (or Fullerton Bay sibling options) and some Marina Bay properties — many premium suites in the Marina Bay area offer private balconies for skyline/harbour views; great for couples who want city lights and harbourfront dining nearby. (See Fullerton Bay and other Marina Bay properties for balcony suite options.) (tripadvisor.com.sg)

Mid‑range, boutique & local flavour

• Hotel G Singapore (Middle Road / Dhoby Ghaut) — runs “Greater Room with Balcony” categories and has had romantic stay packages (movie‑in‑the‑balcony, picnic setup) — good for couples wanting an intimate but city‑central stay. (straitstimes.com)

• Village Hotels (Katong / East Coast) — some branches (e.g., Village Hotel Katong) have rooms with balconies overlooking vibrant neighbourhoods or the coastline; romantic if you like East Coast food-and‑stroll evenings and a cozier local vibe. (tripadvisor.com)

Value / practical options

• Orchard Rendezvous Hotel (Orchard) — Club or some room categories listed with private balconies overlooking greenery; convenient for couples wanting Orchard shopping access with a quiet balcony to unwind. (tripadvisor.com)

How to choose (quick tips)

• For private plunge pools/terraces and a resort feel: pick Sentosa (Capella, The Barracks, W Singapore at Sentosa Cove).
• For dramatic city/bay skyline and rooftop dining: pick Marina Bay properties (Mandarin Oriental, Fullerton Bay, Marina Bay Sands suites).
• For boutique/quirky romantic packages (movie‑night, private dining on balconies): check boutique hotels (Hotel G, some Sentosa boutique properties) and seasonal packages.
• Always confirm at booking that the specific room type you want includes a balcony/terrace (room names and inventory change; request the room category in writing and ask for photos or confirm on the hotel’s booking page).

If you’d like, I can:

• Narrow this to a shortlist of 3 based on your date, budget, and whether you prefer beachfront (Sentosa) or skyline (Marina Bay), or
• Check current rates and exact room availability for specific dates and request the best room categories with private balconies.

Which would you prefer?
