Pam, look at The Rembrandt. Nothing fancy but clean, large room and very friendly staff. Harrods is one block walk and it is directly across the street from the Victoria & Albert Museum. Close to Hyde Park. And one of my favorite London restaurants - the San Quentin. It's been almost 4 years since I was there but would return in a heartbeat, especially since you won't be spending much time in your room. Got a great rate through BA back then. Have no idea about rooms for 3, but I was with a girlfriend so we requested a room with 2 beds. They didn't have a lot - if my memory holds - but got one with a great view of the Museum.
