Nice place that's within walking distance to Amsterdam Centraal & restaurants.
There's an elevator in the main building that will take you up to the 2nd floor. But once you're in the the apartment, you'll have to go up a set of rather steep spiral staircase. Be careful as you go up or down as there are no rails, especially if you have luggage.
Room was clean and simple. Other guests are hosted in a room next door. Everyone shares the same restroom. Wake up earlier or stay up later. Restroom lights are sensor activated. Ladies, it goes out when you're in the shower stall washing your hair with soap all over. So bring your phone as a back up light just in case, or just shower in darkness. No big deal. You'll have to get out of the shower stall and wave around to get the sensors activated again.
Communication was fine with the host. Very accommodating. Make sure to text them in advanced about arrival times and do not assume host will be there at check in times posted on listing as they have work too. If you don't have data, make sure you get a data card/ hop onto WiFi at the airport of something and text the host.
