Its a great place, I haven't been to Bristol before and the views are rather good since the space is on the top floor. There was plenty of desk space and both wired and wireless connections available and they also have meeting rooms which were getting some good use the day I was there. The atmosphere was friendly and everyone had a smile for me, even though I was a stranger and only there for the day. The office is part-shared by sustrans so there were other nice ethical touches, like fairtrade tea and coffee and a good selection of recycling options.
I had a great day and will be looking out for opportunities to use The Hub again - either in Bristol or elsewhere. Thanks!
