International Schools in Bishkek

We will be moving to Bishkek with our three children (5 years old, 3 and 1) mid August and we are looking for an international school for our two older ones. Can anyone recommend a school? Through the internet I found:
- QSI International School of Bishkek
- Silk Road international School
- Hope Academy of Bishkek
- European School in Central Asia
... but it is difficult to make oneself an opinion only from their website. I would be grateful for any information and advice from people who know these schools. Thanks!
