I am from Latvia, and it's very similar to Estonia, with the exception of language, of course, plus I have some friends there. In short, you'll get tall slim girls with pretty faces, good beer, cheap alcohol and cigarettes and food and basically everything else in general, along with free wifi almost everywhere. Clothes and gaming stuff are slightly more expensive than in other parts of Europe, though. And for £8 a day you wont get the most spectacular accommodation.The small cities like Tallinn and Tartu are very beautiful, but I can't really comment on the nightlife there
The downsides are the winter, which is colder and darker than in the UK, and you might be shocked by stuff like customer service and the seeming rudeness of people. Nobody talks on the public transoprt or queues or bus stops, because Estonians are a pretty introverted nation, but they open up eventually, if you are friendly towards them.
Hope this helps, and you can drop a pm if you're interested in any other aspects
