Katja's house is bright, stylish and spacious, and only a stone's throw from the Museumplein and Vondelpark so it's perfectly located for getting out and about in the city. The beds were comfy, and the shower was an unexpected MVP - there were like 3 different faucets going on in there! A full on rainfall showerhead, a regular detachable showerhead, plus side jets. Very cool.
Katja herself was lovely, providing us with a welcome basket and local beers for our stay, which went down a treat. She also gave us great pointers on things to see and do which we would have completely missed out on otherwise.
10/10 - would stay again, and would recommend it to others too.
