Stayed for a night here, and here are what I noticed:
Matthew the receptionist dude is cool and really helpful!
The hostel location is 2 mins walk from Fira bus station (easy to go to port, if you travel by ferry)
Many cafes and supermarkets around so you wouldn’t have issue with food, or cafe
The rooms are not too bad, stayed at 10 people room, and because it was off seasons, only 4 people were there
The shower and toilets are big enough to not get squashed!
Overall, it was a good stay for 20 euro per night!
