Here's my honest review:
The pros:
+ The emplacement: How convenient it was it's right in the heart of Edinburg, you can walk to all the cool spots nearby. I highly enjoyed that.
+ The staff: There were all really cool, grateful to all of them.
+ The decoration: How cool they've made it for an urban hostel.
+ The price: Very convenient.
+ Private bathrooms + showers.
+ Awesome breakfast: Highly recommend to take the added option, it had a sweet selection and the cost was great too!
The cons:
No elevator: If you are in the third floor like I was with a luggage, get ready to do some stairs.
The above pods: If you have a place in the upper parts, you will have to climb, just to be aware.
Moving toilet floor: I had the impression that floor was moving, I think it was because it was the movement of the car from the street below.
Thank you for having made my trip a great one!
