Room was small, no wardrobe, nowhere to hang clothes, some of the plug sockets didn't work properly on bunk beds despite checking plugs were plugged in at mains. We didn't like the fact that when we arrived and on first use the toilet was blocked. Jeremy came the following morning with a plunger, and this improved it marginally. However, it reverted back again, so we were using the communal toilets on floor 2. It wasn't until on the 4th day Jeremy came with an auger that it finally unblocked properly.

Bad area, very loud streets with little noise blocked by windows/walls.
The fact that it had laundry facilities, but that’s about it

The size of the room, the bed set up in the shower set up. It was very weird.
