We really liked the location and the staff were friendly and helpful. But we had three issues. First, the room was prepaid via Hotels.com however this did not register on the Guest House check in system. After showing the receipt, I was told not to worry, but at check out the file was not updated. It was really uncomfortable having to defend this again since we need to rush to make our train!
But this was a minor nuisance in light of two other issues. First, our room faced a courtyard and drunken folks were still laughing it up loudly at 3am! We leaned out the window and asked the to quiet down in English and Dutch but they ignored us.
Second, the heating was not easily adjusted and the room was way too warm. Most rooms therefore had their windows open. Bad for noise and especially bad for the climate. These were disappointments which we hope the Guest House will work on in the future.
