I come here when I need a place to study or work, away from the office. There seems to be lots of different activities going on but I mainly look for a table where I can plug in my laptop. There is complimentary WIFI access but the last time I was there I was not able to connect.
The area I am usually at is relatively quiet with several others studying or working, on their laptops. There is one security guard stationed close to the front entrance.
It's not a bad place but it's not something to brag about either. It serves my basic purpose. Facilities are maintained as well as they can be for an older library.
