Are you single? If you are single, you will stay in single room and the room rate is quite expensive. If you want to check hotel, go to
www.paristravel.co.uk but the price is per person not per room. If you are a girl, be careful because france is not very security at the moment and london also. Take care. If you visit uk, I recommend travel lodge or other big b and b but don't stay at small one, It is quite dangerous.
Good luck
Take care
***If you visit ukand get the problem, you can contact me in my e-mail, I will try to help because I come from hk, also.***
