Thank you so much for being a part of this community! It's so nice to hear that the site has been helpful in making your dream a reality.
If anyone is making a trip through Tbilisi, I can confirm that Mark's Hostel is a cozy intimate place with all the heart and soul of an old school backpacker hostel. It's a perfect success story to encourage anyone who has been thinking of opening their own hostel to take the plunge.
All the best Mark!
