This letting agent is just absolutely horrendous - terribly irresponsible and unprofessional. I moved in to their property about 4 months ago, and it's been many problems after problems, and we're still having problems. When we first moved in, one shower system was completed detached and one radiator wasn't working. Another unit in this same property under their management did not have heat or hot water when the tenants moved in. When I asked the staff why so many problems, their response to me was, "We have about 70 units there, we cannot make sure that each one has everything working properly."
When you raise a request for maintenance, you never hear back from them. You have to insist that the problem is urgent, or keep hounding them before they take any action. Repairs also take longer than expected when it's finally done.
You'd be lucky if you never run into any problems with this agent. If you do, I've learned that they just don't really care. Save yourself the risk and don't rent any property from this agent.
