Possibly the worst estate agents I've ever used in my history as a landlord. They don't answer the phone, respond to emails and when you try to go to their branch, chances are it's closed. The deposits they take aren't held in a deposit scheme.
There's no point dealing with these guys for guaranteed rent, cause when they don't get their way (i.e. you insist on deposits being in a deposit scheme) they say the tenant hasn't paid the rent and don't pay you.
That's with the guaranteed rent scheme, the one they sell to you as we'll pay you rent regardless of what happens with a tenant/property.
