Tjalle's place was a delight to stay, newly renovated, and very well furnished. The relaxed, peaceful location is also excellent with very good local eateries he recommends in a written orientation. The transit system is very easy to use, just download the Amsterdam transit app and hop on the tram or bus to pay for a day pass. (Multi-day passes have to be purchased near Central Station, it seems. And the taxi to the airport can be booked online.) We arrived early in the day and Tjalle was very responsive. The one note I'd make is the stairs are typically narrow and steep. for older Dutch houses/apt buildings. Upon arrival if you have a heavy suitcase, split if up before going up (then when leaving) for safety sake.
