Perhaps not the cheapest but the best value for money we have found is Jurys Inn at Chelsea Harbour
Chelsea Harbour is awesome - some fantastic boats are moored there
A couple of superb restaurants nearby - Gordon Ramsay was filming "the F Word" whilst we were there in one of the restaurants
Robbie Williams and Michael Caine have apartments there
There is a huge childrens soft play centre next to the hotel
You will be parking your car in an underground car park with Ferraris and all sorts of sports cars next to you - some of the Ferraris had 3 inches of dust on them - looked like they hadn't been used for a couple of years - God knows who owns them
No doubt as this area develeps further this hotel will get more expensive
We paid £79.50 per night for a family room for 4 which for the location I thought was very good
