Our DS (11mo) is at Teddies West Dulwich (in the converted church on Gipsy Road). He has been going full-time since he was 7.5mo and he really loves it. The staff are lovely and although there are quite a lot of babies in the baby room they all seem very happy there. The only other place we looked at was Dulwich Day Nursery (Asquiths), which was quite a bit more expensive and we didn't like as much. Little Starz (more down in West Norwood - not sure whereabouts in Crystal Palace you are) also has a good reputation I think. Price-wise, Teddies seems more affordable than some - not sure how old your LO is? The older they are, the cheaper it gets.
