This was indeed a unique experience and I loved every minute of it. The space itself is one of a kind - pictures try, but you just have to be there to experience it. Kristine and her daughter were very easy to communicate with - quick responses and solutions (if required). The area is an excellent place to stay, aside from the many restaurants, cafes, museums, historical sites within walking distance I cannot more highly recommend the tea shop just on the street in front of the apartment. During part of my trip I was under the weather and list my voice - I was made a special what I call magic tea, given a blanket and sat reading a booking in an atmosphere I could not find more relaxing and homey despite a 7hour time difference from my actual home. I recommend this place for anyone who wants a unique accommodation in a great city. (Note: you can lose track of time, as it is underground, so set your alarms!! The weather was mostly great when I was there, so I would open the door for sunlight and outside air at times)
