This was a good stay for our party of 9! It wasn't immaculate inside, but it was very good for the price in London! I would definitely consider staying here again.
Pros: It has an elevator, plenty of space, good bathrooms, and it was about a 15 minute walk to the Underground with little ones.
Cons: The kitchen has suffered obvious water damage at some point. It's top floor and can get hot (lots of windows to open though). Near hospital so you hear sirens often.
