Our family of 4 spent one week during the Christmas at Lara's place - it was great in all respects!
Hammersmith is a good location overall - with its shops and all, a nice WestLondon area - and the apartment is close to the tube and the buses. Apartment came fully furnished - including washing machine and dishwasher - and a fully equipped kitchen (and also comfortable beds) - with all the small things & bric-a-bracs to really make you feel at home, including a good library of books, tapes/DVD's. Good heating, and apartment newly refurbished.
And it is this feeling of "really being at home" that added to our trip, as it makes you feel a Londoner - a local - and not "simply a tourist. Shopping your groceries, taking out the garbage, a beer at the local pub..
A very interesting experience overall- complimented by small things like finding milk/marmalade/bread for our breakfast, and even a champagne bottle for NewYear's!
Strongly recommended.
