Klaas is a warm and welcoming host! He's very easy to communicate with, in person or via whatsapp. His place is in the outer suburbs, so you get a taste of real life in Amsterdam, living like a local. The tram stop is right nearby, and trams come and go all the time, straight to the center/main train station. We got our 4-day GVB passes at the AKO store in Schipol, between the florist and the train ticket windows. My brother and I stayed on the 4th floor of Klaas' home in the spacious, window-filled room. The views of the sunrise and sunset were lovely, as were the simple, everyday goings-on in the neighborhood. It got cold when we were there, but we stayed warm at night. Klaas brought up a space heater in case we needed it. There is a cute old town, Sloten, in walking distance of Klaas' place, as well as a functioning windmill, so you can easily sample a bit of quiet, small-town Holland should you want to escape the hustle and bustle of the city. There is a small strip mall close by that has a grocery store (with free wifi!), ING ATM machine, cheesemonger, bakery, fishmonger, and a bookstore, among other things. The gentleman who works at the cheese shop is super nice, and gives you samples! We got superyummy haring with pickles and onions on the side nearly every morning from a little fish stand that they park each day across from the grocery store. Look for the awning. You can sit on a little wooden bench and snarf it up right after they hand it to you, cut into pieces with a toothpick provided as a sort of utensil. Klaas has furnished the room with a coffee machine and electric kettle; coffee and tea are provided as well. We kept our milk in the mini fridge located one floor below. There are some excellent English language travel magazines/publications on the shelves in the room. There is also a TV for watching Dutch language cartoons, etc. All in all, a great setup. I look forward to staying with Klaas when I come back to Amsterdam!
