My three friends and I stayed in Hostel Casaltura's bunkbed room for four, which was nice and clean. We enjoyed our room immensely, however, the room could have used another power outlet. When we arrived at the hostel, we were buzzed in and showed to our room. There is a very big and wind-y staircase, which can be a hike to walk up. It would have been nice if the staff would have been more friendly and offered to carry our bags after a very long 15+ hour journey. The staff was rather cold and unwelcoming. These minor inconveniences were incomparable, though, to the prevalence of cats and cat hair throughout the property. The sofas, tables, and floors were not clean and filled with cat hair. What's more, we saw the cats not only lick all the ceramic mugs, but also lick the spouts of the watercooler. Unbeknownst to us we drank contaminated cat water! As someone who is incredibly allergic to cats, I had no idea the property had cats or that I'd be ill the entirety of my stay. Management needs to be up front with guests about pets before guests book.
