The Berkeley is well-known for its clever Pret-a-Portea tea time creations and its Burberry Trench borrowing program, making it a clear choice for the fashion-minded. (Not hurting is that Harvey Nick's is just two blocks away.) But The Berkeley is also known for its holistic Bamford Haybarn spa, its rooftop swimming pool (which gives kids a designated swimming hour) and outdoor movie nights. So it really does have something for everyone. Of course, as long as you can afford it.
Rates for a superior queen room at The Berkeley, which is the starting room category with a different but still stylish look, start at about 360 GBP ($600USD) a night. The balcony king, which is the top room before the suites category begins, start at 520 GBP ($862USD). This is pricey getaway for sure, (welcome to Knightsbridge!) but all the amenities inside the rooms are worth it.
For comparison, the Mandarin Oriental across the way has slightly bigger starting rooms but with a seriously dated decor. They also charge 15 GBP for their WiFi per day. So for this Friday night, while The Berkeley has a superior king room for $660 a night on Expedia and the Mandarin Oriental has a courtyard king for $653, we'd rather pay the extra $7 and get the free WiFi and the better-looking room.
If you still want to be in the area but not at these prices, The Baglioni Hotel down the road has rooms starting at $400 a night on Expedia, but the WiFi is an extra 14GBP a day. Or if you're really on a budget and don't care about location, then consider The Generator which doesn't sacrifice style for cheap rooms.
