DCL used The Chancery Court hotel in Holborn in 2010 centrally located and easy to get to.
I would say firstly ask which airport are you coming into? As that will help decide location for the hotel.
If say you come into Gatwick I would say
- Victoria.
- London Bridge/ Tower Hill.
As both have connections by train to the airport and also Dover by train.
If you come into Heathrow, maybe West London,
- Kensington
- I would say Paddington but see below.
- Lancaster Gate
- Expensive, Park Lane, Dorchester, Mayfair,
- Holborn if you will use the tube, Piccadilly line.
The coach transfer organised in this group leaves hotels in the County Hall area,
Avoid
Due to major construction work on Crossrail Europe's biggest infrastructure project an West> East Rail tunnel that is under construction now and until 2018
Avoid
Paddington, Bond Street, Tottenham Court Road. Farringdon, Liverpool street, Canary Wharf.
These all have major access holes for stations and lots of construction traffic.
Cheaper often overlooked.
Try Stratford Westfield.
You may know it as the home of London 2012 Olympics and the Queen Elizabeth park, there are new hotels there and as the games have gone good rates and ten minutes to London by Tube.
If you say an area or a hotel i might be able to check it out for you, I travel around all of London all of the time a different place each day.
Thank you so much for your suggestions! I'm pretty sure that we are coming into Heathrow and will rely on the tube for getting around.
