Costa Colonia - Riverside Boutique Hotel
Contemporary and residential. Clean lines, abundant natural light, and a relaxed riverside atmosphere. Think Palermo Soho apartment, not Barrio Histórico guesthouse.
Book a River Loft, River Suite, or Super Loft for actual Río de la Plata views — the standard Loft and Suite face the city side
Why It Matters
Billed as the first boutique hotel in Colonia del Sacramento, designed by architect Martín Gómez. The location is the real story: the promenade and beach are across the street, sunset views over the Río de la Plata are unobstructed, and Buenos Aires is just a 60-minute ferry ride away. Every room has a kitchenette and a balcony, which is genuinely rare in this market.
Costa Colonia sits right on the waterfront promenade in Colonia del Sacramento — facing the Río de la Plata instead of the cobblestone streets everyone else is here to photograph. It's a contemporary 4-star property with around 60 rooms, all with kitchenettes, private balconies, and more space than you'd expect. The hotel feels more like a well-designed apartment building than a traditional boutique — modern blonde wood, floor-to-ceiling windows, crisp white linens. Refreshing, given that the rest of the town leans hard into colonial nostalgia.
Where You'll Stay
5 room types available
LOFT
City-facing room on the quieter side of the building. Still spacious and well-lit at 40 m², with a kitchenette, private balcony, and all the basics — microwave, electric kettle, minibar, flat-screen TV. Good option for couples or solo travelers who don't need a river view and want to keep the rate down.

The entry point for actual river views. Same 40 m² footprint as the Loft, but oriented toward the Río de la Plata and the promenade. You get the sunset from your balcony. Kitchenette, single balcony, same comfort level as the standard Loft — just a better view.
