Would 100% recommend booking with Euroventure if you're going interrailing!! I went with two friends for three weeks and we had such an amazing time. It was so easy and there was no stress because it had all been planned for us- we just followed the Euroventure schedule and we never missed a train or got lost! Some of the rooms we had were so amazing. Our reservation at a hostel in Prague got bumped up to a Penthouse apartment for the price of a six bed dorm!! Interrailing was such an amazing experience and if, like me and my friends, you're students who have deadlines and essays and have no time to map out your holiday then this is the way forward, Happy travelling :)
