So actually I didn't end up staying at RK Hostel. Hotels.com completely misrepresented the room that I had reserved; their photo showed a basic hotel room with two beds side by side, and they said "one room, two beds." But when I arrived it was a bunk bed and I was staying with someone else who I didn't know.
I was shocked and sort of gobsmacked. The hotel staff was amazing. I talked to Rita at RK Hostel at 10pm on Wednesday night, explained my situation and she told me they understood that it was not my fault and they would waive the fee completely. She could not have been nicer.
Staying in a room with strangers was not for me, but I have to say, every single person on staff that I met was nicer than the last, and so I wanted to make sure I left a review to say so.
