Getting to Arnauds place from Schiphol is easy. After getting the 397 bus to Rejiksmuseum (~25min ride) it's a 6-8min walk to get there. Uber is faster, but more than 4 times the price. For someone like me, the location was great - right in between the museums and the city center but quiet enough to get a good nights sleep without the need to listen to British football songs. ;)
Less than a 10 minute walk will take You anywhere You might want to go on Your first visit to Amsterdam.
The place is decently equiped. A great classic movie collection, music CDs that will suit all tastes, some good books and a high quality audio and video system. A Nespresso coffee machine with some capsules will help You to get through the rough mornings which might happen.
On the top floor there are two rooms with decently sized beds - one a comfortable king size double bed, the other a pull-out sofa which could probably fit 2 people without much discomfort. The balcony is spacious and quiet. There were only 2 of us, but 3 or even 4 people could spend time there with relative comfort.
The only problem we had arrived only after my friend sprained his ankle while walking through the city. It got swollen, hurt like a m.er with every step and the only restroom was downstairs from the bedrooms. The stairs were quite steep. You get the picture. Surely, it will not be any problem at all for a person with full mobility. I wouldn't even think twice about it in normal circumstance.
Another thing You must be aware of - this place is Arnauds home. It has his clothes in the closets and some of his stuff in the bathroom. If You want a longer stay than a couple of days, I'd recommend talking to Arnaud to arrange a spare drawer or some closet space for Your stuff.
Overall, the neighbourhood is safe and clean. The neighbours I've met were friendly and welcoming.
If I get the opportunity, I'll visit Arnauds place again in the future.
