Eco Tree Hotel Causeway Bay

Location & Transit

Set on Mercury Street just off Electric Road, Eco Tree Hotel Causeway Bay sits in the quieter, more residential eastern half of Causeway Bay, a few streets removed from the retail crush around Times Square and Sogo. The property is roughly a five-minute walk from Tin Hau MTR station on the Island Line and about the same distance from Fortress Hill station in the other direction, giving guests two route options onto the rail network rather than a single chokepoint. From either station, Central is roughly seven minutes away by rail. Surface transit options include the historic Ding Ding tram system, with stops on Electric Road within easy reach of the hotel entrance.

The Tin Hau MTR station itself takes its name from the small temple a short walk from the hotel, built by the Hakka Tai clan sometime in the mid-1700s after, according to local legend, a red stone shaped like an incense burner washed ashore and was taken as a sign from Tin Hau, goddess of the sea and protector of fishermen. The temple predates every tower now standing around it by roughly two and a half centuries, and it is one of the few fixed points in the neighborhood that has not moved, been rebuilt taller, or changed use since Causeway Bay was still a fishing inlet rather than a shopping district.

The building sits within a stretch of Causeway Bay that has stayed largely residential even as the district’s western half filled with department stores and flagship retail over the past several decades — a reminder that Causeway Bay was never planned as a single continuous shopping strip but grew that way outward from the harbor, leaving side streets like Mercury Street quieter and more locally oriented than the glass towers a ten-minute walk west.

Accommodations & Layout

The 99-room vertical property maximizes its urban footprint through efficient spatial planning, a design constraint shared by most of the boutique towers that fill in Causeway Bay’s side streets, where individual plot widths rarely exceed what a single tong lau lot once measured. Rooms range from compact Standard configurations up to Harbour View Suites, some featuring floor-to-ceiling glass that frames slices of Victoria Harbour and the surrounding skyline, depending on floor and orientation. In-room furnishings run practical rather than lavish: an electric kettle, minibar, in-room safe, wardrobe, and flat-screen television are standard across categories, with blackout curtains and a private bathroom finished in tile and glass rounding out each layout. Interior planning leans on integrated millwork and space-saving fixtures to make the most of square footage that, in a district where land ranks among the costliest in the territory, comes at a real premium per square meter. Beyond the room, the property runs a small but functional service list: gym access, dry cleaning and laundry, a 24-hour front desk handling currency exchange and luggage storage, plus a snack bar for guests who would rather not go looking for a late meal. It is a compact operation by design, closer in scale to the boutique properties that have proliferated across Hong Kong Island’s side streets than to a full-service convention hotel.

Neighborhood & Surroundings

Surrounding the property is a dense grid of retail centers and local dining establishments. Guests step out directly into a food landscape built on Cantonese congee shops, roasted meat eateries turning out char siu and soy chicken from parked butcher counters, and modern cha chaan tengs serving milk tea and baked pork chop rice alongside the international dining towers of Windsor House and Fashion Walk a short walk away. Victoria Park lies roughly two blocks west, offering public tennis courts, a swimming pool complex, and open green space adjacent to the Causeway Bay Typhoon Shelter, where working sampans still moor alongside recreational junks — one of the few working harbor uses left on this stretch of the Hong Kong Island shoreline.

The hotel’s own environmental positioning is more than a name. Under the same “Eco Tree” branding that covers its sister property in Sheung Wan, the group runs a book-sharing exchange for guests and reports working with a local recycling contractor to keep more than 90 percent of its collected plastic water bottles out of landfill — a genuine, if modest, operating detail rather than a marketing flourish. It sits inside a broader regulatory shift: since April 2024, Hong Kong hotels and guesthouses have been barred from automatically supplying free single-use plastic-bottled water and miniature toiletries in guest rooms, a rule that pushed the entire sector, eco-branded or not, toward refill stations and bulk dispensers.

Local Taste

The immediate area carries its own food story, distinct from the mall-anchored dining a few streets west. The public Causeway Bay Market on Electric Road — a government-run wet market rather than a retail food hall — anchors a cluster of small kitchens and stalls nearby that predate most of the surrounding towers; locals still route around the chain restaurants on the main roads to reach them for roast goose, stewed beef brisket, and clay-pot rice. Within a few minutes’ walk, guests can also find Chiu Chow-style congee kitchens, a legacy of the wave of Chaoshan-region migrants who settled the eastern side of Causeway Bay through the mid-twentieth century and brought a distinct, thinner rice-porridge style with them that still sits alongside the thicker Cantonese congee more common elsewhere on the island.
