Andrea was the loveliest and most accommodating host you could ever wish to meet! The apartment is ideally located in a quiet/residential neighbourhood close to all the areas people usually want to visit when in Amsterdam (e.g., with tram 12, you can get to Museumplein in 20 minutes, while with tram 4 you can quickly get to the central station).
If you wish to visit other cities, you have three train stations close-by: Amstel, RAI and Zuid.
In just 1 week, we managed to visit Rotterdam, Kinderdijk, Haarlem, Leiden, Den Hague, Delft, Edam/Volendam/Monnickendam/Marken, Utrecht and almost all of Amsterdam's districts (excluding the center, as we find it way too touristic).
