I've stayed at Kai's place twice now, for a week or two each stay. It's an excellent spot for one or two people, in an interesting neighbourhood just slightly beyond the classic tourist zones of the city. I like cooking there, working there, having visitors. There's a great butcher, terrific bakeries, an outstanding cheese shop, fruit and vegetable stands, straight-up grocery stores, plenty of cafés of every type.
And since Kai put in the shower door, the bathroom –– as full of character as a tiny room can be –– is great. I sleep like a baby there, even if the apartment is RIGHT on the street, and the time I spend working there is always a pleasure.
The ONLY reservation I have: giving Kai's Kitchen a great rating will make it slightly less available for me. But I'll always go back.
