The Annex meeting space is well equipped, comfortable and spacious. It works quite well for non-profit board meetings.

Our experience in using the Annex has been nothing but positive. With the number of conference rooms available, it has been easy to book board and/or committee meetings. The facility is clean and very well maintained.

I have monthly meetings at The Annex and always leave happy. The rooms are clean and well equipped. Everyone there is very friendly and it's easy to book. I have had zero issues and highly recommend booking for your next meeting.

This Place is really cool, I like the fact there is a podcast room, and rooms to drop in to do my work. If I could recommend anything possibly changing the temperatures of the individual units
