Can't fault Nik as a host- he was very fast in responding to messages, met us for check in, was very friendly, offered useful advise, made it clear he was available for any problems (lives upstairs and checked we had his phone number), but then left us to it without any intrusions - which is exactly what we like in a host.
The apartment is in a brilliant location- under 10 minutes walk from centraal station (we managed an hour from stepping off the plane, getting through the airport, on the train and into the apartment) with the vast majority of the city centre attractions being within 15 -20 minutes at an unhurried walk, even less if you are cycling inclined. Youre maybe a dozen paces off haarlemerstrat which is very convenient for a lot of amenities, I had expected it to be noisy because of this, but having spent longer in the apartment than expected we were surprised how quite it got and how early it got quiet.
Looking at the listing before booking I had kind of expected "cosy" to mean small, for the price and location I was willing to take small. On getting there we discovered that the photos are all really accurate rather than flattering- the space is a really good size for a couple,and it was cosy- the bed is very comfy, thick curtains give a real feeling of privacy, we we're there during snow and overnight temperatures down to -6c and the apartment was plenty warm enough throughout our stay, the wifi was fast enough for streaming netflix- cosy is definitely meant in a good way.
Having a kettle rather than just the coffee machine is also a bonus over many places in Amsterdam so we could make tea the way we have it in England!
Would stay here again without hesitation.
