Moving to Genève advice on housing, expenses... (Geneva)

Hi there!

I am moving from Luxembourg to Genève next 18th of April Protected content I am starting at IATA the following Monday.

It is going to be my first time living there and I want to ask for some advice on housing, living expenses, partying, mobile phone company to use, and so on...any advices?

Furthermore I basically do not know anyone so it would be great if someone contact me to have a coffee or so and like this I can start to enjoy Genève from the beginning.

Please do not hesitate to PM me or answer directly here.

Thanks a lot in advance,
