I choose Charlotte Street Hotel.
Location: Located in a great area close to 2 London tube stations. Almost 20 very nice restaurants across 2 adjoining blocks
Lobby/Look of Hotel: Very European. Hotel on street. Very unassuming but clean and nice
Room: Excellent. Very clean. Well furnished. Great bed linen. Bathroom very clean with 5 tub and shower.
Hotel Restaurant: Great for a drink if you come in late at night. Restaurant closes around midnight but they move you to comfortable sofas in their cozy living room with an open bar and an "honesty" service (you sign for your drinks)
Service: The staff is very friendly.
I read these coments so I choose Charlotte Street Hotel.
