Well, what to say, I've been in Rome a couple of weeks ago, and definitely fallen in love with that city. Speaking some italiano on my next trip would be really cool :)
So, what I though is something like finding a native Italian speaker who could teach me some basic Italian in the next months - starting from pronounciation, reading, and conversation in a relaxed atmosphere... The only hard constraint is that we'd need to meet during lunch time at Uni Vaihingen campus as I work there - e.g. 1-2 times a week, and maybe on weekends at my/your place or somewhere in the city.
...and if no Italian appears, i'd consider improving my Spanish as well. I learnt Spanis up to the conversational level couple of years ago, so you would mostly have to chat with me so that I get a feel of the language again and pick up some new phrases :)
If interested, please PM me with your contact info!
Cheers,
Ana
