About This Property
This terraced flat is located in CARDIFF, CF14 3PG. The property offers 38.91m² (419 sq ft) of compact living space with 3 habitable rooms. It is a period property with Victorian or earlier origins. The property holds an EPC rating of C (76/100), meeting the government's target standard for energy efficiency. The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The solid walls lack insulation.
