Everything was great. All the staff was very kind.
When I arrived, they told me that Hostelworld did´t send the mail for reservation of my room and that I would be able to sleep there 1 night. Or I could go to another Hostel recomenden by them. Also, the Hostel doesn´t have the name "Siagon Mini Hotel 5", but the same address. I´ve never understood if was really the hostel were I booked or it was a scam (that informed in the Lonely Planet). Besides this, the hostel was good, but a little bit confusing because of this missunderstandings.
The staff and the rooms are excellent!!!!
