Robert and family made us feel very welcome and even kindly helped carry our heavy luggage up the stairs. As I mentioned to Robert, the photos matched the apartment exactly, so it was just as we expected -- a very clean and comfortable place, with just the right amount of room for my family and all the amenities we needed (including a washer/dryer).
The apartment was also a short walk to the Anne Frank House and a slightly longer walk to the Rijksmuseum and one of the canal cruises.
We thought the apartment was great and Robert was an excellent host. He made a great suggestion to get in line early in the morning for the Anne Frank House, and as a result, we didn't have to wait in line for hours. Thank you Robert and family!
