Thanks for all your suggestions. Can you please suggest which area is the best to stay in London to cover all the places in a better way. My budget is 250 EUR (4 NIGHTS) for 2 people.

You should have no trouble finding a good place for that budget. (We only stay at a really inexpensive place!)

My only suggestion is stay within a block or two of a good tube line. I like the District Line (and the part of the Circle Line that duplicates it). It has stops near a ton of great sights....but that's just an opinion.

Get a street map and mark your sights...then get a transport map or two and choose your area.

You'll find all the transport maps you'll need on the TFL (Transport for London) sight:

€250 (£200/$300) a night (very plush budget) or for all 4 nights together (most likely, hostels or cheap B&Bs in the suburbs only)?

Ahhh...Patrick...it did not occur to me that OP meant 250 EUR for all four nights. :-)

On our four trips (from US), we stayed at the Cherry Court Hotel...55 or 60 GBP per night. I'd recommend that strongly. Tiny, tiny rooms, but all en suite, clean, and wonderful people running it.

Located a couple of blocks from Victoria Station, so it has good tube access, including a line from St Pancras (for coming from Eurostar -- which I assume applies to the OP, since his/her budget is in Euros and coming from Paris).

Thank you so much Patrick and ssander. I will check Cherry Court Hotel.
