Joan's apartment was clean and nice. Also an area was safe and quiet. We were two moms and two teenagers living there for one week. There was enough space for all of us to feel comfortable.
The tube was really close. Actually, in another bedroom you can hear the brakes of the tube early in the morning. If you have problems with sleeping, it could be good to have some ear plugs with you. There were several nice restaurants in surroundings. We ate some wonderful crepes there.
Also Natural History museum was in a walking distance.
