Hi Sam, welcome to the Hostel Management community!
I love your enthusiasm. It sounds like you are exactly the type of person who would thrive in a hostel atmosphere, and your background will make it really easy for you to adapt to the work.
You’re already off to a great start, too. Writing down all the ideas you have to make your own dream hostel helps to paint a clear picture in your mind of how you want it to be and what you would need in order to achieve it. Every time you have a brilliant idea or you see something you love in another hostel, write it down so you don’t forget to implement it later. Once you start the process of opening the business it is easy to lose track of little details, so those notes will be invaluable to you as you progress. Next comes choosing the location where you would like to live. After that you can start to calculate how much you would need to invest and how much it would cost to run a hostel in your chosen location.
Please keep us updated as the project moves along.
In the meantime, I’m curious which of the hostels you have seen so far has come the closest to the ideal hostel you’re planning for yourself?
