The post seems slightly melodramatic and certainly doesn't mirror my experience finding an office for our company in the same area.

I'll agree that trying to find an office in London online is pretty futile - the best thing to do is leave the desk and take a walk.

Allocate an afternoon or two to pound pavement and start calling all the letting agencies with signs on the outside of buildings.

In one afternoon I managed to get two viewings sorted for the same day and several for the following days. Most of the agents would email us a daily summary of new properties they'd get in which met our requirements (1500sq ft, Old Street area etc.)

We had our new office sorted within two to three weeks. 6 month rolling lease.

Only fly in the ointment is that I'm still getting emails!
