The room is as the pictures show; small, but comfortable. The place does face out onto the street and there is a bit of traffic noise at night, which may be a concern if you are a light sleeper. The location is 10-15 minutes by tram/train to the centre of Amsterdam, with both stops less than 400 metres from his place. As for Arne, he was easy to get in touch with, friendly in the brief interaction we had with him and very accommodation. We were able to leave our bags at his place before we officially checked in as we were heading away for the day and wouldn't be back until late. Thanks for letting us stay!
