The website All Europe Rail focuses on backpacking across Europe. Among other things, it provides some resources which include several lists of hostels people can stay in. Two sites that are referenced are Hostels Europe and Backpacker.
Hostels are really cheap hotels that travelers stay at for a day or two when traveling. There aren't really very many elder hostels, and there's very few hostels in the US. They're usually in Europe.
To save money you stayed at hostels during your two month vacation in Europe.
To find hostels in Europe, you can use websites like Hostelworld, Hostelbookers, or Booking.com. These websites allow you to search for hostels based on your destination, dates, and budget. You can also read reviews from other travelers to help you choose the best hostel for your trip.
Hostels are cheap places to stay in Europe. These aren't like hotels--there is usually a community bath, and less furnishings in the rooms. In smaller hostels, rooms are shared and may even have no beds, just places for a sleeping bag. However, hostels are a fantastic way to easily afford lodging while traveling through various countries.
The age limit for staying in hostels in Europe varies, but most hostels have a minimum age requirement of 18 years old. Some hostels may also have maximum age limits, typically ranging from 35 to 45 years old. It is important to check the specific age requirements of each hostel before booking.

Yes, hostels are only in Europe. There are retirement lofts and town houses that would be the same thing as the hostels found over seas. All you have to do is decide where you want to retire and look at what they have to offer.
Backpacking it, staying in hostels and using the slow trains for transportation makes for the cheapest travel around Europe.
To make it on the cheap, hostels and hiking can help.
I would talk to travel agencies who have worked with hostels in Europe. I have read that they can be a bit more expensive. If you are capable of taking care or yourself and don't need assistance then it is just as practicable to plan a trip on your own, do what you want to do, see what you want to see.
