[Metalab] Looking for a relaxed place / coworking space to work out from

Hey all, I'm looking for a place in a somewhat relaxed, comfortable space to work out from, starting February. I'm not that interested in these overly straight, business-y, mainstream coworking spaces but would rather like to work with a couple of people out of a relaxed Atelier/Flat/Private Office. Bonus points for being close to the 3rd district and the possibility to smoke a cigarette without having to go outside :) I'm wondering if anyone here knows something / has a free desk in theirs / wants to rent something like this in the near future. Thanks! - Chris
