Leonardo was accommodating with my check-in time, as I got their much earlier than his expected time. Ferry terminal is pretty close by (approx 10 mins) that takes you to Centraal, the walk to/from the ferry can seem a little sketchy at night but there is nothing to be concerned about; there's always bikers around.
I would recommend mapping the location on Google maps (or take screenshots if you don't have internet) cause it can be a little tricky the first time. I would've used Uber if I could, especially if you are walking with lots of luggage.
Room was as expected​ from the pictures, it's small but cozy. Can get a little cold at night, which probably isn't a problem in the summer.
For food, options are a bit limited but economical options like jumbo are close by also a really good Turkish restaurant not too far away that is open later than most places.
