We had a great experience staying in a typical Amsterdam apartment. Yes, the stairs are steep but that is part of the experience and very normal for the city. Laurence and Jos were great giving us all the information we needed.
The apartment was in a great location for us. It was an easy 20 minute walk to the centre of the Joordan, only 3 or 4 minutes to the tram and a short walk to the park. Lots of stores and places to eat in the area.
