The apartment was clean and well-situated: in a quiet street, about 5 mins walk to the tram stop, near restaurants and supermarket. We just had difficulty with the 3 flights of narrow stairs. While there have been heads-up on this, and having been to Amsterdam before, seeing the actual stairs and bringing the suitcases up and down left us breathless. I think it would be more suited for travelers with cabin-size luggage.
The bathroom was small but well-maintained. Basic necessities were provided as promised. I just found the keys a bit challenging to use. Petra gave instructions on how to work them, but it does take practice and familiarity. She was planning to change the main door lock, though, which would be helpful.
All in all, it was a fine accommodation more for the younger set. What I truly appreciated was Petra's immediate response to our queries and initiative in getting us as much info to guide us.
