The list price of £2,250,000 seems reasonably competitive considering the location, although a lack of square footage data makes a precise price-per-square-foot analysis impossible. Similar properties in the area are listed at comparable or higher prices, suggesting the price is in line with market expectations. However, without knowing the size, a definitive judgement on value cannot be made.

Based on the provided photos, the property appears to be well-maintained, although not entirely new or modern. The kitchen and bathrooms show signs of being updated to a good standard. The living areas show slight signs of age and wear, which is normal for an older property in London. It does not seem to require significant renovation; however, some updating may improve its appeal and value.

Onslow Gardens, South Kensington is a highly desirable address in one of London’s most prestigious areas. The location benefits from excellent proximity to numerous highly-rated schools (e.g., Our Lady Of Victories RC Primary School), and multiple transport links (though distances are noted as being reasonably far), and is within walking distance of shops and amenities. The area also has a very high standard of living, which further contributes to its desirability.

The property offers a substantial terrace which offers significant outdoor space, especially for a property in central London. While not a large garden, the terrace’s size and usability make it a positive attribute.
