Hi guys!!

I write from Italy, and I hope my english is clear enough for you..

My name is Chiara, and I'm 30 years old..

In septmber, I'd like to spent a week in London (or in Paris, not decided yet), and I'm looking for a good hotel in in...

I have a baby...consider this..

A pretty hotel, without spending a big capital in money!!

Thanks a lot

try having a look at this link here:
http://destinia.com/hotels/hotels--in-london/great-er-london/great-britain/europe/22187/en
they have a wide range on offer, carrying details about the hotels and their locations. most hotels are pretty much child friendly, and shouldnt cost you any extra money.
hope this helps you!
