I just checked in at the Conectas coworking space today, and it turns out they are running a major discount right now. If you pick up a monthly plan and pre-pay for at least 3 months, they will give you a 50% discount.
As far as I know, they haven't posted this anywhere; I can't even find it on their website.
If you are looking for office space and might like trying out a coworking space in Providencia, you should stop by and check it out!
I just signed up for my 3-months this afternoon, so I'll be hanging out at Conectas a lot (hopefully that comes across as a positive factor :P). If you want to come by and look at the space, send me a message. I don't have any special access or anything, but I'd love to meet more entrepreneurs and professionals in Santiago (:
Conectas is located by Santa Beatriz c/ Providencia, around the corner from the tourist information center. Visit the website at Protected content
