About This Property
This semi-detached flat is located in CAMBRIDGE, CB22 5LG. The property offers 40.84m² (440 sq ft) of compact living space with 2 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (66/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (70/100).
