Positives first! It is located only five minutes from Queensway underground station, so easy for travel purposes. The breakfast is also good enough - toast, cereal, and a selection of hot and cold drinks. I never really go for fancy breakfasts anyway. The bunk, with the curtains pulled over, offered me a good degree of privacy and the 11:30 lights out rule is ideal for a dormitory. The staff were also helpful when I lost my keycard, and they were happy to answer any questions.
Downsides! Don't pick here if you have any sort of mobility issue. There are multiple floors, no automatically opening doors and it has a lot of turning stairs. Pretty, but not good for those who are less-than-able-bodied. If you are particularly affected by the smell of weed, avoid. There seems to be near-constant smoking outside and it does often waft indoors.
