They managed to leave us feeling very bitter, and this was despite the fact that the flat itself was lovely. While they were not shy about disturbing us on a regular basis and checking whether the flat was kept in good condition, they failed to fix the problems in the flat. And most outrageously, they charged us for replacing items which were never there or were broken to begin with. I am simply speechless. They operate like a machine, and they would not respond to us unless it is something to their liking.
For potential tenants, I'd recommend this: whenever you are about to rent a place, make sure it is not managed by Rushbrook & Rathbone.
