Central London Hotels

What is a good hotel in Central London that has an indoor swimming pool?

I am looking for a hotel close to some sights and the underground. One that offers an indoor pool would be great for the kids in my group. If it offers breakfast too, then that would be perfect but not necessary. I just want a good, clean, central hotel that will be close to all the tourist attractions.

This hotel is very central and has a pool.
