The best-located of Madrid's four WeWork spaces.
There isn't an awful lot to separate each of the four WeWork locations in Madrid. Most feature a single core floor for All Access Members, which can get reasonably crowded depending on the day. None of the sites feature any of the more plush amenities you may come to expect elsewhere on the continent like staffed baristas, relaxation rooms and showers, but they're generally well maintained, well-lit and comfortable.
They make a noteable effort across each site to run two events per week, usually centred around some local food or drinks, which may be useful if you're looking to create connections in the city. There's a decent range of local discounts for nearby food and coffee shops which may be worth taking a glance at also.
You can access all the sites 7 days a week and they feature all typical WeWork amenities such as free beer (17:00-19:00) and coffee. Even in the mild spring mornings, without the A/C over the weekends, the rooms can get uncomfortably stuffy.
Of the four, the site at Eloy Gonzalo felt like the best located to spend your work days. There are numerous coffee shops within a 5-minute walk, a large BM and Dia supermarket within close proximity and countless bars centred around Plaza de Olavide a short walk away. If you don't already have WeWork access, there are likely better/cheaper options to be found across the city, but if you've already got access then they're convenient and reliable options.
Other WeWork locations in Madrid
Calle de Goya - The standout feature of this site is the large outdoor terrace which none of the other offices possess. Probably the comfiest of the four in terms of soft furnishings if you're intending on spending plenty of time on the sofa.
Castellana 43 - A well fitted out space but the smallest working area of the four, and it can start to feel pretty cramped when it gets near capacity.
Castellana 77 - Comfortably the worst located and least enjoyable of the bunch. Acts more as a foyer for other corporate residents in the building and not a particularly enjoyable place to spend the day. Poor selection of lunch options in the immediate area.
