Finding a location in A'dam that will accommodate 4 people and not break the bank is difficult. For this reason I decided to check airbnb, and found Louis's place. If you're looking for a clean home with a short walk to public transportation, this will do you well. The public transportation in A'dam is super convenient, so get a tram ticket before you leave the station. You'll be set. Mind you, it's a five minute walk from the stop to his house. But this is standard about most everywhere in the city.
Be aware it is more on the outskirts. Again, though, it's no further from Centraal train station by tram than other locations that might be considered more city center.
The flat is very clean, though with a bit of a musty smell in one of the bedrooms, due to moisture (as it is below street level). Louis had a dehumidifier running at the time. This wasn't an issue for us. There are steep stairs going down to the two bedrooms, so if you are very tall (over 5-9) you need to watch your head at one point. These stairs are very typical of most homes in the city. You'll be hard-pressed not to find a place with stairs.
The beds are comfortable. Reality is that if you are spending time in the home, it is better for three people, as there is only a (comfortable) couch to seat three. But it sleeps four comfortably, and we weren't really there to spend time in the house.
I rated the furnishings as basic, but the reality is that it is between a mix of furnishings with a very nice kitchen. The coffee maker was my favorite part (and why I booked here). It grinds the beans fresh and makes awesome espresso. (Make sure you get a primer on how to use it. This is not a basic machine.) A quick walk to one of the many markets or fresh bakery just down the street, then back for a fresh coffee in his beautiful kitchen, and I was in heaven. (And it saved a lot of money on breakfast.)
A very lovely stay.
