I recently rented a house through Churchills, and it has been a very smooth transition from a problematic previous letting agency to one who I would say is very professional - which makes a nice change! Rebecca, at the York branch, was extremely helpful - from house viewing to collecting the keys - and took the headache out of the process.
With how crazy the current housing situation is in York, it's great that there is a letting agency who still put customer ease of service at the forefront of their day-to-day activities.
