Raymond's place is located directly in the center of Amsterdam but a little off the main tourist areas. Therefore its still easy to reach anything worthwhile on foot while avoiding most of the traffic. We never used the train for anything since it was so easy to reach anything by foot and while Raymond recommends taking the train from the central station, we easily reached his place in less than half an hour by walking.
The flat is modern and luxurious and made us feel at home the minute we walked in.
Raymond was great host who offered us any help we needed and brought us a superb breakfast to our room every morning at a time of our choosing.
We highly recommend staying with Raymond on your next trip to Amsterdam, we are definitively booking with Raymond again. :)
