Everything is great save for one detail — a small toaster oven appliance is needed in the kitchen.

I was just staying overnight before a very early flight but the carpet in my room was disgusting.

Loved it. Everyone was super nice. The location was PERFECT and room (I had one of the private ones) was exactly what I needed for my stay. Will absolutely stay here again.

This was my first time at a hostel. And I didn’t know what to expect. I made sure I read the reviews and just like the reviews said this place was amazing. Front desk was very friendly. I was able to check in my bags early since I had a very early flight And leave them at 10 AM which made it very convenient to be able to start sightseeing. Rooms were clean and common areas were kept clean so far, very pleased, especially being a solo woman traveler. Only thing I would add is make sure you bring your own lock because if you don’t and if you have stuff to lock up, it’s a $10 charge for a lock at front desk.
