This estate agent is the single worst one I've ever come across, and I've had troubles with other agents before.
Problem 1: We told them the intercom was broken the *day* we moved in, still not fixed 8 months later. I even know what's wrong - but can't get them to bloody fix it.
Problem 2: The flat was filthy when we moved in; Mould growing on windows, carpet black with dust.
Problem 3: 6 Month tenancies - Don't be fooled, this is just so they can charge you an extra
