Xiong and his place were perfect for my stay in Amsterdam--truly a clean and quiet retreat. The apartment is lovely, easy to find, and just a short bus ride from all the central sites (the bus runs often and at all hours). I stayed in the smaller room which had a comfy single bed, small desk, room for my belongings, and just enough space for my yoga mat. Xiong was very welcoming, flexible with my check-in time, and ready to offer a cup of tea in the morning and evening.
