Nick's place is a great place to explore London. Very nice neighborhood a short distance from Baker St. tube. Nice living space for the family to hang out with a large dining table.
Believe the reviews that the lockbox to access the space is very difficult. Never experienced a worse lockbox. Horrible location below knee level and almost impossible to see the labels on the buttons. The advance instructions give 3 different varieties of the lockbox, so hard to prepare. Have those instructions ready. You will need them.
Main bedroom is very nice, but mattress in second bedroom has seen better days. Painful springs.
Overall, would stay again, as once you figure out the lockbox, it is a great place for your home base in London.
