I was a tenant in a 2 bedroom property and was dealing with this agent for about a year. During our tenancy, the main door of the property had been broken as a result of an external assault. Also, at the end of the tenancy they ask us to deduct a sum from our deposit for professional cleaning of the property, without providing a professional cleaning during check-in, on top of those for the external door, which obviously was not our responsibility.
Moreover, we had contacted them many times during our tenancy period in order to make a PEST control in the property, as we had seen mice in the kitchen (most probably because of the fish and chips shop located under the property), but we got no response.
Finally, we had to deal with the TDS in order to achieve a reasonable agreement for our deposit.
