My boyfriend and I used Euroventure to book our interrailing trip. We had a long consultation process however the staff were extremely helpful and when we took some time to decide whether or not to go ahead they were super helpful and delighted we were still interested. I was a bit worried at the start as I wasn't sure what type of accomodation they would book on your behalf even though it ended being better than anything my other friends booked themselves and so maybe so more clarity about the form that is filled out once you pay which allows you to select your travel preferences. All in all we had a great experience in each city. Th travel booklet they put together is the best thing ever. Having the trains time in advance was unreal and we were able to judge then which time would suit us to leave for the next city. The times were always correct and matched the interrail app so it was super reliable. There were a few mistakes in our booklet like for example we could have gotten off in lesce bled from the villach train instead of going munich to villach (we had to do this), villach to ljubjana (which stopped in lesce-bled) and the ljubljana to lake-bled. we wasted about 2.5 hours backtracking on ourselves and although we saw the sign for lesce bled we weren't confident we should get off because the booklet had been correct up until then. Similarly there was an error as to the dates of our stay in split in the booklet. Again these issues are very minor but if they hadn't occurred we would have had a flawless trip. Some of the accommodation was amazing. Budapest was almost a 5 star hotel whilst still being a hostel. There was a little confusion at the start as our first train was the night train and we weren't sure what arrival date to put it as I had heard the 10pm/6am rule has been changed so we rang them to clarify and they answered straight away. The issue only occurred because the 'fill out the interrail form' which was included in the pack was sent out before the rule changed so was none of the company's fault whatsoever but they were great for helping us. More clarity in the breakdown of the price would be appreciated just to know if we could have done it any cheaper but overall it was very good value. The maps in the booklet of how to get to each train station were super helpful but maybe a picture of the front of the place would also be great. I would definitely book with them again as they seem to know the best hostels to stay in that are more like hotels whilst still being reasonably priced. Myself and my Boyfriend thoroughly enjoyed our trip.
