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.

OT301 is a cultural centre in the former building of the Film Academy at the Overtoom. It’s a good place to get drunk, watch a movie or to eat. It's not too expensive, like most other places in Amsterdam, and the ambience is good.
Candles, incense and fragrance oil to lighten up your place, this place carries tons of it. You might be greeted by the slightly unusual owner, sitting behind the counter smoking a cigarette. It's an authentic little store.
