Four of us had a great stay last weekend. Esther was responsive in communication & even came downstairs to let us in a bit early, as she heard us chatting outside. Any problems were ironed out quickly: we had a slight problem with the heating in the garden studio (or perhaps we couldn't work out how to use it). When we came back it was sorted, the studio warm & Esther had left us a bottle of wine & made us a very nice print for the inconvenience.
It's ideal for two couples sharing, and a great base for exploring the city & De Pijp. For me & my wife it was ideal, because we used to live a couple of streets away, so we felt like we were home again, and it was fantastic for seeing how our old neighbourhood has changed (it's gone even more upmarket, with bars and cafes every other step, it seems).
The flat is pristine, stylish, very spacious, and the kitchen in the main studio is equipped with everything you need (apart from a bottle opener: we couldn't find one in the drawers, so left one as a gift to the apartment). The beds are comfortable. The garden studio has a small fridge, coffee maker and kettle, too.

There's a big Albert Heijn supermarket opposite, and good bars on every corner of the street. I may be biased, but you get a better sense of what Amsterdam is really like staying in this part of town than you would in the centre (which is only 15 mins by tram from a stop a few minutes' walk away). The river is a 15 min stroll away too.

I loved staying here and next time we're travelling as four people to Amsterdam, I would certainly come back.
