Was greeted by the musky smell of damp carpets, went to check in at the reception, and got a key for our room on the second floor. Walked in to check the conditions, found blood on the sheets, a telltale sign of possible presence of bed bugs, so of course we check the area. It didn't take long (maybe 10 seconds) to find the first bedbug along the wall behind the bunk bed. As someone who has had their life uprooted for the better part of a year due to a bed bug infestation in new york city (half my belongings are still wrapped in plastic till we can be sure the bed bugs are all fully dead), I know what is and what is not a bed bug. These were bed bugs, fully grown adults who have recently fed.
We took pictures, exited in a hurry, and brought it up with reception. Our booking was cancelled without much of a fuss, but it was very clear this was not a surprise and nothing will be done about it anytime soon. You may be able to get a room here for cheap, but you run a (very) large risk that you will not only get plagued with the bites of bed bugs who will feed on your skin at night in large numbers, but will infect your belongings and turn your life upside down when you bring them back with you to wherever you go next. Bed bugs are a big deal, and a hostel that won't bother to replace bloody sheets for new guests is a hostel that you can trust will not deal with an infestation problem, leaving you, the guest, with the consequences.
