3 years ago we asked the same information to the forum
here. We had a 2 year old and 3 year old at the time. We came on a 2 year contract and then extended it by another year. We are now returning to the UK at the end of the year. Having reread my original post I realise it quickly became a place which descended into a very polarised argument of lovers and haters. Argentina is a constant paradox but then it does make it an interesting place to live.
We live a long way out of the city in Hurlingham which is lovely for about two blocks but not very pleasant beyond that. This is significant. You'll be living in amuch more pleasant area than ourselves however we live in a house with a small swimming pool which is great however it is covered in bars from a security point of view.
We're returning for a variety of reasons mostly because we miss our family but also because we used to like going for walks in the beautiful English countryside at the weekend , not having to worry about our security each time we go out, ability to get post from Grandparents (forget about getting parcels - they don't get through), difficult to buy quality goods unless they're exorbitantly priced, the need to drive for hours to see anything of geographical interest (However there are some stunning sites to be seen but it's best to take a plane), bureaucracy, and the urban living can grind you down when you have kids . Also the economy really isn't great as I'm sure you're aware.
So why did we stay for longer than our original 2 years? Having young kids is an open invitation to meeting many lovely Argentine people who really love the family lifestyle. We can go to a parilla every weekend with friends if we wanted to. Also in the space of two years our children were bilingual and for us that has been really important as the benefits of growing up bilingual are significant. Also the food is good and you can eat out very reasonably but watch your weight and don't expect much variety. Pasta, malbec, meat, pizza, empanadas, milanesa, chicken. And of course the climate which is really pleasant most of the year.
We arrived with 8 bags on the aircraft and are trying to leave with 8 bags. It's the best way to go. Do not send over loads of stuff. You'll spend most of the first year trying to get it into the country and most of the second year trying to get it home again.
Feel free to PM me if you want any more info.
Good luck!
