The list price of £6,500,000 is substantial. However, considering the location (Castelnau in Barnes), the size of the property (4,693 sq ft), its apparent condition (well-maintained and possibly recently renovated), and the inclusion of a sizeable garden, the price falls within the range of similar properties in the area, suggesting reasonable value, even if not an exceptional bargain. The lack of sqft data for comparable properties makes a precise per-sqft comparison difficult; however, the overall package justifies the price within a reasonable margin.

Based on the provided photos, the property appears to be in very good condition. It seems well-maintained and recently renovated or refurbished with a modern kitchen and updated bathrooms. While some minor cosmetic updates might be a matter of personal preference, the overall impression is one of high quality and excellent upkeep.

Castelnau, Barnes, is a highly desirable location in London. It’s known for its prestigious addresses, proximity to excellent schools (as evidenced by the nearby listings of highly-rated schools like The Swedish School and Lowther Primary School), and good transport links (Barnes station being relatively close). The area offers a blend of affluent residential character and convenient access to amenities and green spaces.

The property has a garden, which is a significant positive in London. While the exact plot size isn’t specified, the photos suggest a garden of considerable size, providing outdoor space, which is rare and valuable in this area. Therefore, I have given it a higher score.
