Thanks for the hospitality of Lea and her doggy! And lemon tea tastes nice. About 10 mins walking from the metro station, since the ticket in amsterdam is sold in the way of counting time (1h, 1d and more days...except the railway ticket). The key point is to figuer out the route in advance, for it may get the wrong direction even with google map. The brilliant thing is the refrigerator in bed room where has beer and water. On the other side, maybe it is the style of archi in Netherlands. Stairs is very narrow and steep. Just conquer it and explore this exciting city!
