Han's apartment is lovely - very light and modern and recently decorated, so we were very comfortable there. It is an easy tram ride from Centraal Station, and close to the museums and Dam Square, so in a good location.
Although communication was good in advance, we did feel let down with some aspects of the service. Although we arrived at the apartment exactly on time as arranged, the girl who came to let us in was more than half an hour late - we tried calling the mobile phone number provided, but no one picked up or returned our call. The wifi code we were given didn't work, and we only got the correct login on our second day, and we were unable to get the TV to work because there were no instructions as to how to use it. No bed linen had been left for the second bed (a sofa bed in the sitting room), although that was delivered later that evening. I have to say though that the sofa bed was very comfortable to sleep on.
I believe that Han's apartment is managed by a third party which would explain some of the issues we encountered, and I think this also means that some of the personal service is lost. It is a lovely place to stay but the personal touches are missing.
