I think this hotel is overpriced.
I found the bathroom in the solo room to be very strange, the solo room is very compact and the window was very awkward to open. I also saw there was some black mold. Unfortunately there were works going on outside during my stay, which made it unpleasant. The bed was very uncomfortable, it dipped on one side and it was squeaky - clearly the mattress needs changing. The walls are quite then so you can hear the other guests coming in and out - so earplugs are 100% necessary! The staircase was awkward, tight and fairly steep.
The wi-fi is so poor, and mobile data doesn't work properly because signal is sketchy.
Be aware, they also take a deposit- this really surprised me because nowhere when I reserved the room said that!
The only positives about this place is just how close it is to Kings Cross and the staff are friendly.
I wouldn't re-book and im sure you could find somewhere better in the area.
