Comfortably the best choice out of any of the city's four WeWork sites.
Situated just to the east of Plaza de la República, WeWork occupies the entirety of this 38-floor commercial building in the heart of the downtown area.
The main All Access area is based on the 38th floor, offering some of the best views across the city looking out onto the Río de la Plata and far into the distance. Within the top three views from any WeWork I've visited. On the 20th floor, there is a second communal area with the main community bar and a café serving reasonable coffee, sandwiches, and cakes.
The area around the building is ideal to explore during the daytime, with plenty of options for a quick bite to eat for breakfast or lunch.
Magic Coffee - Closest speciality coffee shop, had a great Peruvian bean on during my visit. Super friendly staff.
Empanadas KRYSS - Some of the tastiest and most generously filled Carne Picante empanadas I found, perfect quick breakfast option.
Food Time - If you are searching for a quick lunch, this pay-by-weight buffet is a popular option with local office workers, with an enormous variety of salads, meats, Argentine dishes, and a few local Chinese ones thrown in. Get there before 12:00 before the queues start.
I commuted from Palermo Hollywood and enjoyed the process of heading into the CBD daily. It's around a 25-minute ride on the underground, which was quiet and pleasant pre-7AM. If I was to return, I'd aim to be within a 45 minute walking distance. Worth considering getting a WeWork pass specifically for this site.
Other WeWork options in Buenos Aires:
Vicente Lopez - A huge site with plenty of seating options but, unless staying immediately in the area, too far out. Not as much of a buzz compared to the sites in the city. Great roof terrace for during the summer months.
Ing. Enrique Butty - A ten-minute walk away from Corrientes in the CBD, much smaller and with less dedicated seating. Would not prioritise.
