As you can see from the photograph, the Greenhouse Progress Club has very nice conditions - the floor is one of those Taraflex type materials, which is very comfortable to play on. The tables are DHS T1024 tables, which play very well. The lighting is very good and the walls are painted a shade of blue that contrasts nicely with the ball, and the upper walls are painted a lighter color to increase the brightness of the hall.
The only real quibble I would have with the conditions is the green cloth barrier you can see on the left of the photo - as a long range defender I moved back far enough to step on this barrier once or twice, and when I did I lost all traction with the floor and ended up slipping over. So defenders and lobbers beware when your back is to the green cloth barrier!
