Explain how it works
We compare every 5★ review's word count against the global distribution. Hostels where unusually many top-rated reviews are suspiciously short — way under the typical length — start to look like the staff (or a boost-my-listing service) is padding the score with throwaway praise.
The detector flags reviews that are both top-rated and below a length threshold, then estimates how many of them statistically shouldn't exist. For this hostel we scanned 7191 top-rated reviews and 0% were suspiciously short.
Length z-score: 11.39. A z-score measures how far this hostel's distribution of 5★ review lengths sits from the global average, in standard deviations. 0 = perfectly typical. 1–2 = slightly unusual but within normal noise. 3–5 = strongly anomalous. Anything 10+ means the pattern is so far from the global norm that it's effectively impossible to get there organically.
This is a heuristic, not a verdict — it surfaces hostels worth a second look, not proof of fraud. Read the actual reviews below and judge for yourself.

Reward tied to a review
review for them to store your bag otherwise you pay
They don't have a communal fridge, and the breakfast is 10 euro, its a way of inflating cost. It's fancy the rooms are fine, but honestly I cannot give a hostel without personal food storage a 5/5. And I'm deducting an extra star because it's hostel policy to ask you to leave a review for them to store your bag otherwise you pay for it, so I'm going to weigh down their reviews to counter this policy because it seems a little manipulative. I've slept in dozens of hotels where both of these services were free. Cannot justify a 5 star review, if these sorts of things dont bother you, then enjoy your stay its an "okay" hostel

10/10 for the money
Not enough Vegan options to pay the price. And also the coffee isn´t available for purchase without buying the whole package which is wack. One of the nights there were like 3 guys who didn´t understand that at 2 in the morning we are not switching on the light in the room without turning them off again, which was bizarre. Other than that 10/10 for the money.

在超级市中心位置，去哪都可以走过去。早餐8欧每人每天，需要额外支付。管理非常好，我住的两人女生宿舍，没有睡眠噪音，床非常舒适且大，而且室内卫生！除了人比较多，卫生间是一天一打扫略显有点脏外，其他一切都非常完美！下次在马德里还会入住这个酒店！
