I live on Codrington Hill and love the area. It's fantastic for children with Blythe Hill but also Ladywell fields and One Tree Hill. The Ackroyd Centre is just across the road with regular playgroups, Monkey Music etc.
Well within Stillness catchment but with the option of Dalmain too. Great schools.
There are plenty of good restaurants, cafes and pubs within walking distance, many of which are child friendly. Brockley Rise is very convenient and the shops are useful with a post office, florists, dry cleaners, hairdressers, electrical shop etc. Crofton Park a short walk with a Budgens, Co Op and the lovely Butchers previously mentioned on Ewhurst.
People are very neighbourly in the area and I have never witnessed any trouble/noise on the road. Myself and my family have always felt very safe in the area. Parking right outside your house can be an issue but I always get a spot on the road. In fact, we have so much on our doorstep that we are considering selling the car as it's rarely used.
We are in a Victorian house which I love and is full of character. Subsidence wasn't noted when we had our survey carried out. Properties are quite diverse on the road though.
Transport is great into the city with the overground and regular train service to London Bridge. Gatwick is also easily reached.
PM if you would like more info but a thumbs up from me. Good luck.
