I can't speak to the rooms but I can tell you a little story about this hostel's brand of customer service:
After arriving a bit tired and carsick/seasick in Bocas, I made the decision to stay in a private room at Hostel Tungara for the first night. Knowing that Hostal Hansi was a bit cheaper and would be a bit quieter, I headed over to the hostel later that afternoon, my hair still wet from my shower. Upon arriving, I politely asked the hotel owner if there were any private rooms available for two nights beginning the following day. She told me that while they were fully booked that evening, I could swing by the following morning and a room would be available. She was not particularly friendly but not outwardly rude. As other reviewers have commented, she was brusk.
The following morning, I arrived, as promised, to book a private room for two nights.
"I'm sorry," the same German woman said, "but we are fully booked." How strange, I told her, mentioning our conversation from the previous afternoon. I asked her if she thought rooms might free up later in the day. She told me that they might and suggested I stop by again later.
As I prepared to leave, the strangest thing happened: a young man walked in and asked, in Spanish, if she had any private rooms available for two nights.
"Of course," replied the owner who had, not two minutes earlier, told me that no rooms were available. She promptly led him up the stairs to show him a room. When she came back down, I was more incredulous than angry. Perhaps there had been a miscommunication since we had been speaking English?
"I'm looking for the same thing," I said. "A private room for two nights."
This was when the German manager did a Hulk-like transformation. "I don't have time for this!" she told me in a huff. She angrily told me that the hostel has a "policy" of not accepting clients from other hostels in Bocas and asked me how I could possibly have entertained the idea of another hostel given the fabulous reviews Hostal Hansi gets online. I told her that I thought that this policy was odd (shouldn't the client decide where s/he stays and have the prerogative to do so anytime?) but oddest was that she had lied to me outright rather than simply telling me about her hostel's policy the previous evening. Almost yelling as she retreated back to her lair/office, she told me that she had done so in an effort to be "diplomatic."
Well, Hansi, as it happens I was a diplomat for 6 years... and lying and humiliation are not tactics they teach you in diplomat school.
