The reception room, to the left, is a generous space with lofty proportions, accessed via wide double doors and features space for separate dining and seating areas.
The room is enhanced by wooden floors throughout and traditional sash windows that fill the space with light.
The room's elegant proportions and refined period details create a sophisticated living environment.
The kitchen, on to the right of the hall, is thoughtfully designed with fitted, wooden units, and offers ample preparation space and storage.
The principal bedroom provides generous proportions and considerable built-in storage.
This impressive room benefits from an en-suite bathroom and is enhanced by a broad bank of windows, with views over the gardens.
A well-appointed second bedroom offers comfortable accommodation, while a separate family bathroom serves the remainder of the flat.
