My husband, 2 kids (aged 11 and 9)and I just spent 4 nights in this lovely apartment. I highly recommend it for a family stay. The Underground is less then 5 mins walk away and you are immediately on main lines to all the top locations, ie Picadilly and District lines. The check in system was flawless, the apartment was spotless, and we had plenty of space for the 4 of us.
Luggage Hero and Stasher are both located locally if you need to store your luggage the day you check out so that you can make use of the day.
