Freek replied to our messages quickly and answered all our doubts. We didn't get to meet him as he was away during Easter but a friend of him opened us the door to the apartment and she was also so nice.
The room and the whole flat is exactly as it looks on the pictures. Bright, clean and nicely decorated.
The apartment is well connected. We walked to the centre almost always, we only took the rail at night to go for dinner or at the end of the day after walking all around Amsterdam. The rail stop is just in front of the door and the metro is around the corner.
We really enjoyed our stay and will go back to Amsterdam for sure :-)
