We stayed in the apartment for a week. This was a wonderful time!
Studio is in the very center of the city. You can easily access most of the sightseeings, museums etc. Tram station is in a couple of steps from the apartment. So, getting to Centraal Station is just a matter of 20-30 minutes - you'll be able to get to any city of The Netherlands from there too if you'd like to.

Jacob was very helpful and cheerful. If we had any questions about city or house.

I was slightly disappointed with the apartment itself. Although technically speaking it matches the pictures, it is not like them at all. Furniture is at the same places, pictures are mostly the same, but the apartment itself is very dark. The fact that it was in the basement was quite a surprise for me.

For those who are going to stay there we took a few pictures from the same camera positions as taken by host. Hope you'll find them useful.

In the end, we had a very good time in Amsterdam and really enjoyed it. Place of the house is extremely good. The fact that the studio is dark was not a serious problem for us, but it would be much better if we saw fair pictures of the place before moving in.
