Educa Russian Language School Saint Petersburg - Any experiences?

Hi! I am looking into returning to Saint Petersburg for a short visit after living there from 2009-2012. I am thinking of going to two weeks and taking a one week Russian group course the first week and just relaxing and exploring the second week with my Russian skills a bit more refreshed after many years of not using it. I looked at a few schools, the state universite, Derzhavin insitute etc and I keep going back to Educa. The thing is there isn't much I can find on the internet about this school or blogs/social media of people who have studied there so I can't really get a real review. Has anyone studied with them or knows someone who has studied there?
