OK, the work is done!
Thanks for your help.
Now that Iīve booked the hotel, i can tell you what it is:

Itīs called Fairway
500m distance to Kingīs Cross
An en-suite double room with English breakfast for 60 Punds per night.
The booking is confirmed,
got the tickets for the flight
got the tickets for WDTW( I would take photos of the show, but thatīs not allowed

).
Now nothing can go wrong anymore!
Again, thank you all very much!
R.
