The apartment is managed by Iambnb, who were great to deal with - we were a bit late arriving so the agent met us with the keys as we had lunch at a canal-side bar around the corner. We met Naomi and Joost briefly and they were very welcoming, but we didn't need to bother them for anything during our two night stay because the apartment was beatifully clean and comfortable. The area was lovely - not central but a quiet areas with with plenty of restaurants and shops close by and an easy 20-30 minute walk to the city centre and museums. We'd definitely stay again.
