My partner and I had a wonderful stay at Carel's property. The location was just perfect, with the canal just outside and it being within walking distance to so many of Amsterdam's sights and experiences. The check-in process was really smooth with both Juan and Carel, and Carel was generous with letting us leave our bags at his place before we officially checked in and after we had checked out.
The property was really clean and the description of it was accurate. Great view out the front window onto the canal, only enhanced by the glorious sunshine we had while there. The room was a bit cold in the morning until the heating came on but at the time we were there it wasn't a problem. Also note that the toilet does not have any privacy so you should be comfortable with whomever you are staying with. Nothing was a problem though and our stay was great.
