I would like to recommend a new nursery in London SE1 which is just a 9 minute walk from London Bridge Station. It is called Leo's Den and is for 2-5 year olds. My daughter started there a few weeks ago and we could not be happier with the provision. The garden is lovely and safe, they are learning so much in terms of letters, words and numbers, they do lots of creative stuff including themed days, the food is great etc. etc. - they even have nursery cam - which is brilliant!
