We spent a lovely weekend in Roel & Mirjam's beautiful flat. Everything was clean when we arrived and Mirjam had left some apple pies out for us which was a nice touch :) Had no communication problems and Roel was really helpful in the lead up to our trip. Although checkout was at 1pm on the Sunday, they kindly let us leave our luggage in the flat until 3pm when we were due to leave for the airport.
The flat is in a really nice area, beautiful views overlooking the canal and within walking (or cycling distance) to Vondel Park and good tram/airport links.
Living space was lovely, only negative is that the bedrooms were quite small (for the single room with pull out bed - once we'd pulled the bed out there wasn't much room for anything else). But overall a lovely stay!
