Fantastic experience at this place. Matthijs' is probably the most responsive host I've had, and made sure that check-in was seamless upon arrival.
The room was very clean and comfortable, and equipped with any extras we may have needed (bath robes, wine glasses, coffee supplies, etc). And the absolute best part was the location. His space is a two minute walk to Dam Square, and yet, we had no problems with noise or lights at night.
