We use Regus in NY and LA. 4 and 10 person offices, changing daily or weekly depending on where the sales team is meeting. Works great for us. Everything is clean and it's always quiet. Kitchens are well sized and stocked. We know the reception staff in each location and they do everything we ask.
WeWork was much more expensive and a much noisier and busy environment, especially if you don't get your own dedicated office space, and if you're going to do that then major cities all have tons of subleases which are much more attractive.
