With boutique hotels continuing to launch at a steady rate in the Buenos Aires’ neighbourhood of Palermo Viejo, competition for distinction is key. The latest opening - the third outpost from Argentine group CasaSur Collection – is a 61-room property that includes a spa, gym, outdoor pool and a 235 sq metre rooftop bar, nestled on the hotel’s eighth floor. ‘The terrace is the star of the place...It’s totally unexpected and unique, with unforgettable views of the city,’ says the architect Gieselle Chalu, whose debut into the hotel industry brings a touch of New York, London and Berlin to Buenos Aires. Her signature interiors reveal cosy, yet elegant public spaces and clean, functionally designed rooms with geometric wallpaper, Acapulco chairs and Petiribi wood fixtures. Understated earthy hues set the tone for the entrance lobby with an eclectic mix of wood, cotton, glass and a bold five metre high bookshelf, which sits behind a marble reception.
