Clementi is a mature estate, so amenities are plentiful. Clementi MRT Station (East-West Line) is about 3 minute walk. Clementi Mall is located there and has a supermarket, numerous restaurants and cafes, as well as a library,so it’s pretty convenient.
Nan Hua Primary School (a GEP School, no less) at Jalan Lempeng, so this is useful for those with school-going kids. Pei Tong Primary School is just across Commonwealth Avenue West. Clementi Town Primary and Secondary School is a stone throw away. Moreover, there are many educational institutes in that area, namely, NUS, Ngee Ann Polytechnic, and Singapore Polytechnic.
