AI Summary
This is a well-presented penthouse apartment in one of Cardiff's most desirable residential neighbourhoods, offering modern interiors and a prime Pontcanna address. However, the asking price of £300,000 sits meaningfully above the local comp median of £260,000, and buyers should seek independent valuation to confirm the premium is justified by the penthouse position, finish, and floor area. Key due diligence items include verifying the actual floor area, confirming leasehold terms and service charges, and resolving the apparent conflict between the listed build date and EPC construction data.
