This is a very clean and pristine little apartment. The host lives right below, so that makes the check-in process easy. The beds are very comfortable and bigger than I thought they would be- one room has a king and the other seems like a queen.
There is one full bathroom with a tub and separate shower and one 1/2 bath in the hall by the entrance door. This was very workable in our group of 4 (2 couples).
The kitchen had coffee available and a little area with seating but it is really not for cooking at home if that is what you are looking for. It was not a big deal to us because we were out everyday and only came home to sleep and shower.
I will say the stairs are serious business. They are steep and plentiful (54 in all). Now maybe 54 sounds easy, but lugging suitcases (thankfully the host brought ours up) and the actual boards being so narrow and spiral in a way, it was tough. Be aware. You will need a breather after coming up and check your heart rate coming down because they are steep.
The apartment is quite a ways out from the heart of the city and the canals make for a bit of a walk to get around, but the busses and trains help.
All in all, it was a great stay. The place was spotless and we loved that!
