weel, first of all, it's not easy to find a one/two months work in this field or something alike.
I guess would be easier to find a work as a Waitress,,,,
Finally, the,,, "propina" o "mancia" en italiano es practicamente obligatoria,,,
so you could afford how to get some money,,,,
then, London is so expensive,,,,
and a 1 room flat could cost 1500 euro for month in the centre.
so I guess would be better to take one just near the centre, and go there with the metro,,,
Hoping to be useful,,,
Bye!
