Otto's apartment is lovely and nicely furnished and decorated with taste. We felt like having a little home in Amsterdam. I would definitely recommend the place for a couple. We were two couples and had ample space for us four but perhaps better for two. Otto was available and arranged everything for our arrival. He also gave us great tips and advice depending on what we were looking for in Amsterdam. We followed his recommendations and ended up in really good places that most tourists may not know about. We really appreciated the insight and the delicate attentions when we arrived at the flat. The apartment is conveniently located next to trams and buses taking you to the city centre in 15 min and to the airport in 20 min. It is also 10 min walking distance from Vondelpark. Really convenient and with all the shops nearby. We had a great stay and would highly recommend Otto's place, Otto being such a nice and respectful host.
