Considering the location in St. John’s Wood, the size of the apartment (723 sq ft), and the apparent condition, the list price of £650,000 seems relatively reasonable for the London market. However, without precise details on the square footage of comparable properties and the exact specification of the apartment this score could be subject to change. The lack of details on plot size also suggests a possible lack of external space impacting the final value assessment.

Based on the photographs, the apartment appears to be in reasonable condition. The rooms are clean and well-presented. The kitchen and bathrooms seem modern and functional, while not luxurious. Some minor updating might enhance the overall appearance, hence the score below 7.

The property benefits from a central location in St John’s Wood, a highly desirable area of London. It’s proximity to excellent transport links (Marylebone station is less than a kilometre away), good schools (including outstanding-rated ones within a short distance), and amenities contributes to the high score. However, the specific location within the development and potential noise or other downsides are not known from the provided information, leading to a score below 8.

The property is an apartment with no garden or private outdoor space, hence a low score of 1.
