The Bartolotti is perhaps one of the most beautiful Museum Houses Amsterdam has, built by someone who once was the richest man in the city, but it's a bit hidden in plain sight. These days, it is run by a group of lovely old ladies, who can't wait to offer you tea or juice. You can walk around the house like you live there. You have to ring the doorbell to get in.

The fence around De Nederlandsche Bank on the Frederiksplein is a true optical experience. While passing the building, a rhythmic, dynamic pattern appears and disappears in the trellis of the fence. The figures on the sides of the rails were designed in 1992 by artist Peter Struycken, a pioneer in the area of environmental art and generating computer-program based image, light and colour compositions.

With 24 hr licence to function as club, nights easily turn into days here. De school houses a coffee and a restaurant place, you can literally enter Friday and leave Sunday. :0 Quite in weekdays with great coffee, atmosphere and natural light

Fotomomuseum housed in two monumental 17th century canal houses. 

I love how small this place is, but it offers such amazing quality in cheeses, meats, wines, bread etc.  You can also have lunch here.  Definitely worth picking up fresh food here!
