Here’s a link to a map of the area showing both Earls Ct. (where ICE is) and Stamford Bridge (CAPeuro location) where Chelsea reside (and the Chelsea hotel – http://www.thehotelatchelsea.com/)
Another very good hotel is situated just of the top of the map in South Kensington (nicer area than Earls Court by the way, though Chelsea itself is upmarket) called the “Royal Garden Hotel” (http://www.royalgardenhotel.co.uk/). Here’s the map:
As an Arsenal fan, I’d urge you not to stay at the Chelsea hotel and add to their coffers for new players please 
If I find Sarafina or TheGooner staying there, I’ll be most put out :1Dialog: NB: For the 32Red team, “Chelsea” are a Premiership football club in case you were wondering – It’s not Leeds, nor Swindon, not even Wolverhampton Wanderers, but I think you’ll be impressed how the other half live
For those flying in to Heathrow, get the Tube from there (http://www.bbc.co.uk/london/travel/downloads/tube_map.html – bottom left hand side) and the Piccadilly line – in blue – takes you right to South Kensington which is about 300 yards from the Royal Garden Hotel if memory serves me right. (Out the tube turn left, then left again, end of the road on the left – from memory so check!).
Cheers
Simmo!
