The list price of £1,200,000 seems reasonable considering the location in the affluent Mayfair area. However, the lack of plot size and the relatively small square footage (677 sq ft) for a one-bedroom apartment in this location might suggest a slightly higher price per square foot than average for comparable properties. Further data on average price per square foot in the immediate vicinity would be needed for a more precise assessment.

The property appears to be in good condition based on the provided images. The interior is modern and well-maintained, though some minor updates might enhance its appeal. The building itself seems well-preserved, typical of the area’s period architecture.

The property is located in the prestigious Marble Arch area of London’s West End, known for its high-end amenities, excellent transport links, and proximity to Hyde Park. Numerous highly-rated schools are also within a reasonable distance. This contributes to a high desirability and value.

The property has virtually no private outdoor space, which is a significant drawback in a densely populated area like London’s West End. While access to communal gardens might exist, the lack of private land significantly impacts the score.
