The list price of £800,000 seems relatively reasonable considering the location and size of the property. While comparable data is limited due to missing square footage in nearby listings, the price per square foot, if calculated based on the provided 839 sqft, falls within a reasonable range for Kentish Town. However, the lack of significant private outdoor space might slightly reduce its value compared to similar properties with larger gardens.

The property appears to be in generally good condition, with a modern interior. However, some minor cosmetic updates might enhance its overall appeal. The exterior shows some signs of age, which is common for properties in this area. The roof terrace, while offering outdoor space, appears to require some maintenance.

Kentish Town is a highly desirable area in London, known for its vibrant atmosphere, independent shops, and excellent transport links. The proximity to Kentish Town Underground station and several Overground stations provides easy access to central London and other parts of the city. The presence of several highly-rated schools nearby also adds to its appeal for families. However, Fortress Road itself can be quite busy, which might detract slightly from the overall desirability for some buyers.

The property has a very small outdoor space in the form of a roof terrace. This is a limited amount of outdoor space, especially for a property of this price in London.
