Klaas is a quality host, our stay at his home in Osdorp was smooth and all a first timer in Amsterdam could ever ask for. Klaas provided all necessary information from the start which allowed for a very independent and pleasant stay. Public transportation was extremely effective in moving about the city and directly to the house which is about a 3 minute walk from the Ecuplein stop. The room itself is located on the 4th floor of the house and it is the only room on the floor itself, it was extremely spacious and well equipped as described, there is a sink/mirror in the room which we found to be quite convenient as the toilet and showers are on the 3rd floor. I would recommend this stay to anyone who may be considering. I will definitely return.
