I have stayed all over London with the exception of the stratospherically priced hotels. I recently stayed here at this location in the Exec apartments for a week. Very nice accomodations. Clean, well appointed room with kitchen. No access to the Concierge lounge for apartment guests however, and lower point values. Two things I did not know when booking. Very conveniently located for numerous high-quality dining choices, and two closely located malls for additional good food choices or shopping. Not too much interaction with hotel staff after arrival, but what I did have was quite nice. Nice enough health club, but needs a TV. Tube station to Jubilee line is 8 minute walk away, and the high-speed ferry pier is 10-minutes away for a more scenic 15-minute ride into the city. I will defintely come back. I paid $175 pounds per night for a 1-bedroom apartment, full kitchen. Comparable hotels in town are at least double that, without the extra space.
Stay on the East side of the hotel. I was on the West side next to the light rail station, and you hear every train coming in and out.
