The cost of Eurolines.com bus was 70 Euros and 20 plus hours, the plane is about 95 Euros however arrives very late. The cost of going to the airports is of EXTREME importance and should be figured out before purchasing a discount ticket. This cost can be more than the cost of the plane ticket because they use weird airports. I think the cost of the train would have been maybe 150 Euros, I should check, however the trains are very expensive for international travel, and definitely not Hobo Barefoot Travel, more Mama Money Travel.
I coordinated with Hostelworld.com to find a Hostels with a Kitchen available, I have found I need to avoid moving during the weekends because the weekend party people use up all the rooms. http://www.hostelworld.com
I am not a big fan of Hostelworld, because their setup is only about making money, however they presently are the main player. Gomio.com is interesting however the same format. http://www.gomio.com
I will find the name of the Hostel on a site, then go do a good search to see if there is a way to bypass the booking engines. These are not guaranteed reservations, there is a five percent or more in my opinion chance you will not have a room.
