Spice Café has amazing desserts and coffee, their carrot cake is a must try. It’s a lively place with good service and free Wi-Fi.
CREC Eixample is nice spacious space, they hold events and have many resources. They have incredible Wi-Fi speed up to 105mbps and cost around $118 for a month.
A good mix of locals and Digital Nomads make CREC my favourite coworking space in Barcelona. It is spacious and comfortable with good WiFi. They have hot desks, private offices and startup events happening here.
