Overall the flat was very nice, had everything you needed to use it as a base to explore Amsterdam from.
Room was spacious with a nice balcony, along with comfy beds and a really nice bathroom with a great shower.
Great location as well, everything you need is close by, shops etc. as well as the centre of Amsterdam only being a 20-30 minute walk.
David is a very nice guy and apart from seeing him at check-in and check-out, he really leaves you to it and allows you to use the space as much as possible which is great.
Definitely would recommend.
