Potentially relocating to Luxembourg for work – looking for advice from locals & expats

Hi everyone!

I may be relocating to Luxembourg later this year if everything goes well with a job opportunity. The role is within the company I currently work for in my home country, so it would be an internal transfer to a different team with broader responsibilities. Nothing is confirmed yet (I’m waiting for the final HR interview), but I’d like to prepare in advance and get a realistic idea of what life is like.

I’m a 24F from Eastern Europe and I’d be coming on my own, so I have a few questions:

1. Accommodation
- Is coliving a good option for someone relocating alone?
- Which websites or Facebook groups would you recommend for finding rooms or shared apartments?
- What should I watch out for to avoid scams?
- Is it realistic to find a room for around €900–1,200/month if I’d like to stay in Luxembourg City?

2. Everyday life
- Roughly how much do you spend each month on groceries, a phone plan, the gym, eating out, etc.?
- What monthly income would you consider comfortable for renting a room, living reasonably comfortably, and still saving a little?
- How easy is it to make friends and build a social life, especially if you don’t know anyone at first?

Also, a very random question: is it common for people to bring homemade lunches to work? I like cooking and meal prepping, but I wouldn’t want to be the odd one out. 😅

Finally, if you’ve relocated to Luxembourg from another country, is there anything you wish you’d known beforehand?

I’d really appreciate any advice or tips. Thank you!
