We had a great time at Jeroen's place!
The room is exactly as shown and described. The bathroom is shared but always clean and tidy and in the 4 nights we were there never once met the other couple we were sharing with, so it actually felt like our own private bath. Bed is super comfy and spacious as well as the room. On the same block you have a shopping mall with supermarket and everything else you might need!

Jeroen is a super-host: knows the city, provided us with a map and gave us precious tips that don't come in guides!

Don't be afraid to stay in the North!
It actually gives you another perspective to amsterdam (a local one) and you'll get to go by ferry to the south side which is a free boat ride (yes, the ferry is free!).
To take the ferry, rent Jeroen's bikes and cycle for just a few minutes until the ferry station.
Still, if you're not the cycling type, just take the 34 bus and in 5 minutes be in the city center.

Definitely recommend it!
