In a few weeks time, I'm hopefully going to be spending a few days in and around Lille, some working, some holiday. For the working part, I'd need somewhere to go in the day, ideally some sort of co-working space or similar.
In Paris, there's an excellent co-working space La Cantine (as mentioned in this question). Regus have an office by the station which includes a business lounge, which in theory ought to be all I need. Unfortunately, the time I tried going there, it was very noisy with lots of people having meetings there (which I've not really found elsewhere), and the wifi was so bad you longed for when an IDBus would park outside so you could use theirs...
Are there any good co-working spaces that'd welcome a visiting tourist for half a day or a day? (Googling found places with a 1+week minimum commitment, which aren't really suitable for me as a tourist just wanting something like half a day or a day). Or failing that, are there any good places (cafes/libraries/etc) I could look at going to?
