We stayed at The Collector for 8 nights in April arriving after a 24 hour flight. After asking Karel if it would be ok to make a cup of tea his reply was "Of course, this is your home" If I was running a B & B I would model it on Karel's attitude. Nothing was too much trouble. He booked museum tickets online and advised us on what to see and what not to see. Our room was at the back, large with a very comfortable mattress (new). The kitchen was well stocked and food was replaced before it went stale. Being able to make our own breakfast when we felt like it was very convenient. I really enjoyed his pancakes and wonderful fruit bread and would look forward to breakfast to see what else was on offer. You could also leave a note if you required something that wasn't there. Also, we took advantage of the nearby supermarket to make simple dinners. It was so easy after a long day sightseeing to return home and relax with a wine and cook up something simple. Running into other guests in the breakfast room was always a bonus. The location was convenient with the museums within walking distance. We wanted to see the tulips in the fields and the bus stop was just near the front door. We also used the tram to go into the city and back to save our legs. However, much of Amserdam can to covered on foot. If all this wasn't enough Karel even did our washing for us without any charge! (twice) We really enjoyed Amsterdam and staying at this B & B made it feel like a holiday. Thank you Karel.
