We had a really good time in Amsterdam and Leah's appartment is a great place to stay. It might not be in the middle of oldtown but it is very close to tram and subway so you can be in town within no time.
It is a family appartment so you should be prepared to meet friends and family and the dog (which is a cutie).
The room is equipped with a little fridge, an electric kettle and a choice of teas and coffee.
We were there for new year's eve and Leah had some friends over for these days so it was a bit crowded from time to time but it all worked out well :)
Also, Leah is a super nice host!
