We recently began rental of a property managed by Ashtons Harpenden and overall they have been great, especially Freya. Everyone we have spoken to has responded to emails professionally and quickly. We had an issue with our dishwasher when we moved in and this was fixed in a few days. The contrast between our old letting agents (LifeResidential Greenwich) and Ashtons is night and day - highly recommended. Edit: Updating my review to include mention of Nicola, who has been fantastic is resolving some move-in maintanence issues.
