International Schools (Bratislava)

Hi everyone! My husband and I are moving to Bratislava in September Protected content we are looking for a good international school for our 3 year old son (where the education program would be in English). We unfortunately will not be able to visit the schools prior to registration, so would greatly appreciate any feedback/experiences that you have had that may assist us in making this decision. We are currently debating between the Cambridge School and QSI. Thanks in advance for your help!
