It's the second time I stayed at Esters place, and I can honestly say it's just the perfect place to explore Amsterdam. Ester is an excellent host: discreet, but always ready to answer any enquiry you may have and very well informed and passionate about her fantastic neighborhood: De Pijp. The apartment is every bit as good, clean and spacious as the pictures suggest, and what they don't tell you is the great welcome the weary traveller gets: fresh flowers, a bottle of wine, some nibbles, espresso machine ... Oh, and there a sturdy bikes available if you want to discover the city like the locals.
My local favourites in De Pijp: Café Schilders (around the corner), Mamouche (best and friendliest Moroccan this side of Marrakech) and Little Collins (best brunch north of Melbourne).
A bit of advice if you come to Amsterdam by car: park at the P&R Olympisch Stadion (a bit of local sporting history in itself). It's just 1 euro per day and tram 16 or 24 will whisk you in 15 mins to the stop Albert Cuyp, just around the corner from the apt.
