D's space is fantastic for large groups, especially students. There were just 2 of us so we had separate bedrooms, but if you had a group of 6 you could sleep there with relative comfort for a very reasonable price. The apartment is located right near a train station, and it is a short 15 minute ride into city center. We were commuting back and forth everyday, and we didn't have any problems. The shower worked just fine for the 2 of us, and the beds were decently comfy. I will say the standout aspect of this stay is the host. D is incredibly kind, wonderfully attentive, and exceedingly flexible. We ended up arriving a bit early, and he let us in. Check out was a breeze even though we made him get up extra early (sorry!). He is gone a lot during the day, but if you need anything (food, advice on where to go, etc.) just shoot him a message or ask him in person, and he'll get back to you quickly. I cannot overemphasize how wonderful of a host he was, and I would definitely recommend D's place for anyone looking to visit Amsterdam.
