The description and other reviews are accurate. It's a very clean, nice space. It's quite small. It's also right next to a gorgeous waterfront. Ash was a clear and prompt communicator, and I would recommend staying here for anyone who is traveling solo and plans to spend the day out and about.
For travelers with a bit of extra time to see more than just the usual highlights in the old city, I recommend exploring Noordpark. (Queens is to Manhattan as Noord is to Amsterdam, sort of?)
