Cannot really find fault with the service I received from Express, I found their staff to be very professional, polite and courteous. They were quick to respond to requests, provided frequent updates and made the experience very easy to deal with.
Express were also quick to arrange my viewing and asked my opinion on the property to give feedback to the vendor. You'd think this would be standard practice for estate agents; however, Express was one of the few agents (from the many that I'd dealt with) that actually did this.
Overall a pleasure to deal with, would highly recommend.
