I personally use Medicover. When you call their hotline, they tell you to press a number for an English speaker. You can then select from a range of services and their English is very high. They have locations all around the center.
I have been looking English books in Warsaw and can’t find anything other than Harry Potter and 50 shades of grey. I looked at ordering from Amazon but the postage costs more than the books sometimes.
I am Polish and I am moving back to Warsaw soon. I have never lived in Warsaw as I was born in the south. What is a good area for kids? I have three kids, so I am interested in a place that has access to parks but also local schools and such. Local transport is not a big issue and my budget is flexible.
