This is a beautiful apartment -- nicely decorated, modern bathroom, picturesque view of the canal -- in an excellent location. We were able to walk almost everywhere. The host was very responsive during our stay, and even though we were unable to check in early, we were at least able to drop off our bags when we arrived.
This is a second floor apartment in a historic building -- be mindful of the stairs! They are very steep and very narrow, which I understand is common in the traditional buildings in Amsterdam. Getting bags upstairs was a challenge, but the rest of the time, the stairs were not a problem.
The only problem with this apartment is that it is situated directly above a restaurant that is a very popular local hangout and is open late (3 am on the weekends). It is very noisy. It is probably fine in the winter, but we visited in August, when it was too hot to close the windows, and restaurant patrons congregate outside on sidewalk tables. We found it very difficult to sleep with all the noise from below.
