We've recently left a rental property (at the end of our tenancy) which was managed by Paramount Properties for nearly all of our 5 years living there. During that time the Paramount team, especially Hollie who was our main contact throughout, were fantastic at dealing with any queries or issues we had. Hollie's communication with us was great and the help we received when we needed it was always quick and efficient. Would highly recommend Hollie and the Paramount team if you are planning on renting in London.
