Meet the lettings team

Our lettings team works hard to ensure all our rental properties get the exposure they need. Unlike other agents, we do not work in competition with each other but as a team to show tenants the most suitable properties. We cover a wide area of West London including Notting Hill, Kensington, North Kensington, Bayswater, Marylebone, Earls Court and Chelsea for both long and short lets.

Liz studied modern languages and business at university but always had a passion for architecture and interior design. Now with over 30 years in agency Liz's reputation in the industry is undisputed. Our business has been built on the back of our clients' respect for her integrity and straightforward approach to everything we do as a brand.

I'm a frustrated architect at heart and I never tire of property. I like to build long-term relationships with my clients; nothing is more rewarding than knowing they completely trust me with their biggest investment.

Annabel Kastelic - Lettings Director

Annabel Kastelic

Director of Lettings

Annabel was born and raised in London and has experienced its vibrancy and culture first hand. After graduating from the University of Portsmouth and obtaining a degree in Sociology, Annabel threw herself straight into the property industry starting at a large corporate estate agency and specialised in short lets during her time. Six years later she progressed onto Mountgrange to offer a more personable and specialised service for landlords, bringing with her an array of experience particularly within the short let market.

I enjoy working in a tightknit team where customer service is the focus, we are able to work together efficiently and seamlessly to achieve the best results for our landlords and tenants alike.

Working with you guys is really low hassle, and you’re always very responsive to my questions! For a first-timer like me, it’s really great to have the support I’ve had from you.
