Absolutely the best department stores in London. The staff are so knowledgeable. It sounds silly but ask a more 'mature' salesperson & they'll probably have 20+ yrs of experience selling the product.

They have a huge baby/maternity section that has everything. If you are completely new then you can book a 2 hour consultation where they take you through everything you will need. Trusted experts.
plan out exactly what you need and from which department before getting on escalators. will save you from having to navigate up and down them - especially when the store is super busy

Great range in homewares and furnishings and lighting for department stores but the service in every area is terrible. Never enough staff and they take no interest in trying to help you.
