This was only my second experience with Air bnb and it couldn't have been a better one!
When we arrived Robert led us up the single flight of stairs to the apartment. Upon first impression you immediately get the sense he is a friendly, personable, happy fellow who enjoys hosting guests. We felt very welcome by him and the amenities he provides, including labeled and numbered maps!
The kitchen had food and drinks in it, the shower was clean and there are convenient hooks for wet towels, the big highlight for us was the bed. It is by far the comfiest bed we have ever slept in other than our own! And he has a fabulous movie collection by the way!
His place is about a 10-15 minute walk from the Waterlooplein Flea Market, 20-25 minute walk from the Red Light District, and a 30-35 minute walk to the Anne Frank house. So it's pretty easy to walk if you're not comfortable renting bikes.
We do not recommend taking a taxi from the airport to his place. It is SO easy to reach by metro. Take the Schiphol Airport train to Centrum Station, then take another train to the Weesperplein Station and you are just a few minutes walk away!
Overall, we loved having his place to come home to after long and cold days/nights of walking and sightseeing. It is easy to find and easy to get around. Everything one needs for touring this beautiful city!
